When we figure out how many file descriptors to allocate for
keeping packfiles open, a system with non-working getrlimit() could

fall back to a reasonable low value rather than dying.

Subversion serf backend in versions 1.8.5 and below has a bug(*) that the
function creating the descriptor of a file change -- add_file() --
doesn't make a copy of its third argument when storing it on the
returned descriptor.  As a result, by the time this field is used (in
transactions of file copying or renaming) it may well be released, and
the memory reused.

One of its possible manifestations is the svn assertion triggering on an
invalid path, with a message

svn_fspath__skip_ancestor: Assertion
`svn_fspath__is_canonical(child_fspath)' failed.

This patch works around this bug, by storing the value to be passed as
the third argument to add_file() in a local variable with the same scope
as the file change descriptor, making sure their lifetime is the same.

* [ew: fixed in Subversion r1553376 as noted by Jonathan Nieder]

Even though "--[no-]edit" can be used with "git pull", the
explanation of the interaction between this option and the "-m"

* jc/maint-pull-docfix-for-409b8d82:
  Documentation: exclude irrelevant options from "git pull"

10eb64f5 (git pull manpage: don't include -n from fetch-options.txt,
2008-01-25) introduced a way to exclude some parts of included
source when building git-pull documentation, and later 409b8d82
(Documentation/git-pull: put verbosity options before merge/fetch
ones, 2010-02-24) attempted to use the mechanism to exclude some
parts of merge-options.txt when used from git-pull.txt.

However, the latter did not have an intended effect, because the
macro "git-pull" used to decide if the source is included in
git-pull documentation were defined a bit too late.

Define the macro before it is used to fix this.

The previous commit c57f6281 (mv: let 'git mv file no-such-dir/' error out)
relies on that rename("file", "no-such-dir/") fails if the directory does not
exist (note the trailing slash).  This does not work as expected on Windows:
This rename() call does not fail, but renames "file" to "no-such-dir" (not to
"no-such-dir/file"). Insert an explicit check for this case to force an error.

This changes the error message from

   $ git mv file no-such-dir/
   fatal: renaming 'file' failed: Not a directory

to

   $ git mv file no-such-dir/
   fatal: destination directory does not exist, source=file, destination=no-such-dir/

When trying to pop/apply a stash specified with an argument
containing IFS whitespace, git-stash will throw an error:

    $ git stash pop 'stash@{two hours ago}'
    Too many revisions specified: stash@{two hours ago}

This happens because word splitting is used to count non-option
arguments. Make use of rev-parse's --sq option to quote the arguments
for us to ensure a correct count. Add quotes where necessary.

Also add a test that verifies correct behaviour.

Since 64a99eb4 git gc refuses to run without the --force option if
another gc process on the same repository is already running.

However, if the repository is shared and user A runs git gc on the
repository and while that gc is still running user B runs git gc on
the same repository the gc process run by user A will not be noticed
and the gc run by user B will go ahead and run.

The problem is that the kill(pid, 0) test fails with an EPERM error
since user B is not allowed to signal processes owned by user A
(unless user B is root).

Update the test to recognize an EPERM error as meaning the process
exists and another gc should not be run (unless --force is given).

This reverts commit 31b49d9b.

That commit taught do_askpass to hand ownership of our
buffer back to the caller rather than simply return a
pointer into our internal strbuf.  What it failed to notice,
though, was that our internal strbuf is static, because we
are trying to emulate the getpass() interface.

By handing off ownership, we created a memory leak that
cannot be solved. Sometimes git_prompt returns a static
buffer from getpass() (or our smarter git_terminal_prompt
wrapper), and sometimes it returns an allocated string from
do_askpass.

Support for grafts predates Git's strbuf, and hence it is understandable
that there was a hard-coded line length limit of 1023 characters (which
was chosen a bit awkwardly, given that it is *exactly* one byte short of
aligning with the 41 bytes occupied by a commit name and the following
space or new-line character).

While regular commit histories hardly win comprehensibility in general
if they merge more than twenty-two branches in one go, it is not Git's
business to limit grafts in such a way.

In this particular developer's case, the use case that requires
substantially longer graft lines to be supported is the visualization of
the commits' order implied by their changes: commits are considered to
have an implicit relationship iff exchanging them in an interactive
rebase would result in merge conflicts.

Thusly implied branches tend to be very shallow in general, and the
resulting thicket of implied branches is usually very wide; It is
actually quite common that *most* of the commits in a topic branch have
not even one implied parent, so that a final merge commit has about as
many implied parents as there are commits in said branch.

git log did not correctly handle decorations when a tag object referenced
another tag object that was no longer a ref, such as when the second tag was
deleted.  The commit would not be decorated correctly because parse_object had
not been called on the second tag and therefore its tagged field had not been
filled in, resulting in none of the tags being associated with the relevant
commit.

Call parse_object to fill in this field if it is absent so that the chain of
tags can be dereferenced and the commit can be properly decorated.  Include
tests as well to prevent future regressions.

On broken systems where RLIMIT_NOFILE is visible by the compliers
but underlying getrlimit() system call does not behave, we used to
simply die() when we are trying to decide how many file descriptors
to allocate for keeping packfiles open.  Instead, allow the fallback
codepath to take over when we get such a failure from getrlimit().

The same issue exists with _SC_OPEN_MAX and sysconf(); restructure
the code in a similar way to prepare for a broken sysconf() as well.
