* 'maint' of git://repo.or.cz/git-gui:
  git-gui: Focus insertion point at end of strings in repository chooser
  git-gui: Avoid hardcoded Windows paths in Cygwin package files
  git-gui: Default TCL_PATH to same location as TCLTK_PATH
  git-gui: Paper bag fix error dialogs opening over the main window
  git-gui: Ensure error dialogs always appear over all other windows
  git-gui: relax "dirty" version detection
  git-gui: support Git Gui.app under OS X 10.5

We were returning the _address of_ the stored item (or NULL)
instead of the item itself. While this sort of indirection
is useful for insertion (since you can lookup and then
modify), it is unnecessary for read-only lookup. Since the
hash code splits these functions between the internal
lookup_hash_entry function and the public lookup_hash
function, it makes sense for the latter to provide what
users of the library expect.

The result of this was that the index caching returned bogus
results on lookup. We unfortunately didn't catch this
because we were returning a "struct cache_entry **" as a
"void *", and accidentally assigning it to a "struct
cache_entry *".

As it happens, this actually _worked_ most of the time,
because the entries were defined as:

  struct cache_entry {
	  struct cache_entry *next;
	  ...
  };

meaning that interpreting a "struct cache_entry **" as a
"struct cache_entry *" would yield an entry where all fields
were totally bogus _except_ for the next pointer, which
pointed to the actual cache entry. When walking the list, we
would look at the bogus "name" field, which was unlikely to
match our lookup, and then proceed to the "real" entry.

The reading of bogus data was silently ignored most of the
time, but could cause a segfault for some data (which seems
to be more common on OS X).

When selecting a local working directory for a new repository or a

When we are being built by the Cygwin package maintainers we need to
embed the POSIX path to our library files and not the Windows path.
Embedding the Windows path means all end-users who install our Cygwin
package would be required to install Cygwin at the same Windows path
as the package maintainer had Cygwin installed to.  This requirement
is simply not user-friendly and may be infeasible for a large number
of our users.

We now try to auto-detect if the Tcl/Tk binary we will use at runtime
is capable of translating POSIX paths into Windows paths the same way
that cygpath does the translations.  If the Tcl/Tk binary gives us the
same results then it understands the Cygwin path translation process
and should be able to read our library files from a POSIX path name.

If it does not give us the same answer as cygpath then the Tcl/Tk
binary might actually be a native Win32 build (one that is not
linked against Cygwin) and thus requires the native Windows path
to our library files.  We can assume this is not a Cygwin package
as the Cygwin maintainers do not currently ship a pure Win32 build
of Tcl/Tk.

Most users set TCLTK_PATH to tell git-gui where to find wish, but they
fail to set TCL_PATH to the same Tcl installation.  We use the non-GUI
tclsh during builds so headless systems are still able to create an
index file and create message files without GNU msgfmt.  So it matters
to us that we find a working TCL_PATH at build time.

If TCL_PATH hasn't been set yet we can take a better guess about what
tclsh executable to use by replacing 'wish' in the executable path with
'tclsh'.  We only do this replacement on the filename part of the path,
just in case the string "wish" appears in the directory paths.  Most of
the time the tclsh will be installed alongside wish so this replacement
is a sensible and safe default.

If we are opening an error dialog we want it to appear above all of
the other windows, even those that we may have opened with a grab
to make the window modal.  Failure to do so may allow an error
dialog to open up (and grab focus!) under an existing toplevel,
making the user think git-gui has frozen up and is unresponsive,
as they cannot get to the dialog.

When cloning a remote repository which's HEAD refers to a nonexistent
ref, git-clone cloned all existing refs, but failed to write the
configuration for 'remote'.  Now it detects the dangling remote HEAD,
refuses to checkout any local branch since HEAD refers to nowhere, but
properly writes the configuration for 'remote', so that subsequent
'git fetch's don't fail.

This fixes my favorite annoyance with the git rpm packaging: don't pull
in tla when I say yum install git!  You wouldn't expect yum install gcc
to pull in gcc-gfortran, right?

With this change, and blanket 'yum update' will automatically pull in the
new 'git' package and push out the old 'git-core', and if the old 'git'
package was installed 'git-all' will be pulled in instead.  A couple of
things do break though: 'yum update git-core', because yum behaves
differently when given a specific package name - it doesn't follow obsoletes.

Instead, 'yum install git' will pull in the new git rpm, which will then
push out the old 'git-core'.  Similarly, to get the newest version of
the meta package, 'yum install git-all' will install git-all, which then
pushes out the old 'git' meta package.

The previous text was correct, but it was easy to miss the
fact that we are talking about "matching" refs. That is, the
text can be parsed as "we push the union of the sets
of remote and local heads" and not "we push the intersection
of the sets of remote and local heads". (The former actually
doesn't make sense if you think about it, since we don't
even _have_ some of those heads). A careful reading would
reveal the correct meaning, but it makes sense to be as
explicit as possible in documentation.

We also explicitly use and introduce the term "matching";
this is a term discussed on the list, and it seems useful
to for users to be able to refer to this behavior by name.

The existing message indicates that an error occured during
push, but it is unclear whether _any_ refs were actually
pushed (even though the status table above shows which were
pushed successfully and which were not, the message "failed
to push" implies a total failure). By indicating that "some
refs" failed, we hopefully indicate to the user that the
table above contains the details.

We could also put in an explicit "see above for details"
message, but it seemed to clutter the output quite a bit
(both on a line of its own, or at the end of the error line,
which inevitably wraps).

This could also be made more fancy if the transport
mechanism passed back more details on how many refs
succeeded and failed:

  error: failed to push %d out of %d refs to '%s'

There may still be some entries from the original index that
should be discarded before we show the status. In
particular, if a file was added in the index but not
included in the partial commit, it would still show up in
the status listing as staged for commit.

Ultimately the correct fix is to keep the two states in
separate index_state variables. Then we can avoid having
to reload the cache from the temporary file altogether, and
just point wt_status_print at the correct index.

In many places we just check if a value from the config file is not
NULL, then we duplicate it and return 0. This patch introduces the new
'git_config_string' function to do that.

This function is also used to refactor some code in 'config.c'.
Refactoring other files is left for other patches.

Also not all the code in "config.c" is refactored, because the function
takes a "const char **" as its first parameter, but in many places a
"char *" is used instead of a "const char *". (And C does not allow
using a "char **" instead of a "const char **" without a warning.)
