Now the history remembers when we have clicked on a graph line
and when we have asked for a diff between two commits, as well
as when we have displayed a commit.

The display when you click on a graph line now uses clickable
SHA1 IDs instead of the embedded "Go" buttons.  Also made the
IDs clickable in the header for a diff between two commits.

This adds a useful "Parent:" line to the git commit information window.

It looks something like this (from the infamous octopus merge):

where all the parent commit ID's are clickable, because the new lines are
added as part of the "comment" string, and thus the regular clickability
thing will match them automatically.

I think this is good. And my random-tcl-monkey-skills are clearly getting
better (although it's perfectly possible that somebody who actually knows
what he is doing would have done things differently).

The effect of this is that it allows Tcl to do the locale-specific
conversion of the input data to its internal unicode representation.
That means that commit messages in Russian or other languages should
be displayed correctly now (according to the locale that is in effect.)

This is based on suggestions by Jeff Epler and Linus Torvalds, but
extended so that we do the switching between the watch cursor and
the normal cursor correctly as well.

Also fixed a bug pointed out by Junio Hamano - I wasn't incrementing
the link number (duh!).

This was triggered by a query by Sam Ravnborg, and extends "git reset" to
reset the index and the .git/HEAD pointer to an arbitrarily named point.

For example

	git reset HEAD^

will just reset the current HEAD to its own parent - leaving the working
directory untouched, but effectively un-doing the top-most commit. You
might want to do this if you realize after you committed that you made a
mistake that you want to fix up: reset your HEAD back to its previous
state, fix up the working directory and re-do the commit.

If you want to totally un-do the commit (and reset your working directory
to that point too), you'd first use "git reset HEAD^" to reset to the
parent, and then do a "git checkout -f" to reset the working directory
state to that point in time too.

Per discussion with people interested in binary packaging,
change the default template location from /etc/git-core to
/usr/share/git-core hierarchy.  If a user wants to run git

$src to the PATH environment variable, git-init-db can be run

This extends the source side semantics to match what Linus
suggested.

An example:

    $ git-send-pack kernel.org:/pub/scm/git/git.git pu^^:master pu

    would allow me to push the current pu into pu, and the
    commit two commits before it into master, on my public
    repository.

The revised rule for updating remote heads is as follows.

 $ git-send-pack [--all] <remote> [<ref>...]

 - When no <ref> is specified:

   - with '--all', it is the same as specifying the full refs/*
     path for all local refs;

   - without '--all', it is the same as specifying the full
     refs/* path for refs that exist on both ends;

 - When one or more <ref>s are specified:

   - a single token <ref> (i.e. no colon) must be a pattern that
     tail-matches refs/* path for an existing local ref.  It is
     an error for the pattern to match no local ref, or more
     than one local refs.  The matching ref is pushed to the
     remote end under the same name.

   - <src>:<dst> can have different cases.  <src> is first tried
     as the tail-matching pattern for refs/* path.

     - If more than one matches are found, it is an error.

     - If one match is found, <dst> must either match no remote
       ref and start with "refs/", or match exactly one remote
       ref.  That remote ref is updated with the sha1 value
       obtained from the <src> sha1.

     - If no match is found, it is given to get_extended_sha1();
       it is an error if get_extended_sha1() does not find an
       object name.  If it succeeds, <dst> must either match
       no remote ref and start with "refs/" or match exactly
       one remote ref.  That remote ref is updated with the sha1
       value.

When we display the commit message in the details pane, any string

We now keep a history of commits that we have looked at, and we

If merging results in an unchanged tree, git-commit-script should not

Also, add "[--all]" to usage().

[jc: usually there is no reason to record an unchanging merge,
but this code path is triggered only when there is a nontrivial
merge that needed to be resolved by hand, and we should be able
to record the fact that these two tree heads are dealt with as a

Every time after servicing the connection, select() first fails
with EINTR and ends up waiting for one second before serving the
next client.  The sleep() was placed by the original author per
suggestion from the list to avoid spinning on failing select,
but at least this EINTR situation should not result in "at most
one client per second" service limit.

    Now, for extra bonus points, maybe you should make "git-rev-list" also

Again I left the v2.6.11-tree tag behind.  My bad.

This commit makes sure that we do not barf when pushing a ref
that is a non-commitish tag.  You can update a remote ref under
the following conditions:

 * You can always use --force.
 * Creating a brand new ref is OK.
 * If the remote ref is exactly the same as what you are
   pushing, it is OK (nothing is pushed).
 * You can replace a commitish with another commitish which is a
   descendant of it, if you can verify the ancestry between them;
   this and the above means you have to have what you are replacing.
 * Otherwise you cannot update; you need to use --force.

If the graph gets to use more than a certain percentage (default 50%)

the only way to customize the percentage is to edit your ~/.gitk

This allows git-send-pack to push local refs to a destination
repository under different names.

Here is the name mapping rules for refs.

* If there is no ref mapping on the command line:

 - if '--all' is specified, it is equivalent to specifying
   <local> ":" <local> for all the existing local refs on the
   command line
 - otherwise, it is equivalent to specifying <ref> ":" <ref> for
   all the refs that exist on both sides.

* <name> is just a shorthand for <name> ":" <name>

* <src> ":" <dst>

  push ref that matches <src> to ref that matches <dst>.

  - It is an error if <src> does not match exactly one of local
    refs.

  - It is an error if <dst> matches more than one remote refs.

  - If <dst> does not match any remote refs, either

    - it has to start with "refs/"; <dst> is used as the
      destination literally in this case.

    - <src> == <dst> and the ref that matched the <src> must not
      exist in the set of remote refs; the ref matched <src>
      locally is used as the name of the destination.

For example,

  - "git-send-pack --all <remote>" works exactly as before;

  - "git-send-pack <remote> master:upstream" pushes local master
    to remote ref that matches "upstream".  If there is no such
    ref, it is an error.

  - "git-send-pack <remote> master:refs/heads/upstream" pushes
    local master to remote refs/heads/upstream, even when
    refs/heads/upstream does not exist.

  - "git-send-pack <remote> master" into an empty remote
    repository pushes the local ref/heads/master to the remote
    ref/heads/master.
