v1.5.4 plans

Please do not take this as the final decision made by the Emperor, whose
subjects now must follow.  This is a sanity-check to see if everybody is
on the same page.

I am not the Emperor anyway ;-)

Deprecation and Removal
-----------------------

 * We have already removed svnimport without giving a deprecation notice
   in the release notes of the previous feature release, which was bad.
   Maybe the users will forgive us.  Maybe not.

 * As discussed on the list, v1.5.4 will ship with the dashed form of
   commands (e.g. "git-commit") on users' PATH by default.  However we
   will move them outside the normal PATH (exact location needs to be
   decided by checking FHS first, something like /usr/libexec/git-core)
   in v1.5.5 so the release notes to v1.5.4 will declare deprecation
   (see the top of Documentation/RelNotes-1.5.4.txt).  We might want to
   keep copies of dashed form Porcelains in /usr/bin but that discussion
   is towards v1.5.5 (post v1.5.4, not now).

 * We also will give deprecation warning for the following features and
   commands in the release notes to v1.5.4, and remove them in v1.5.5:

   - lost-found (use fsck --lost-found);
   - post-update hook (use post-receive hook);
   - peek-remote (use ls-remote)


Topics not in 'master' yet but should be in v1.5.4
--------------------------------------------------

I think the following should go in, along with what we already have in
'master':

 * git-commit in C (Kristian and others)
 * git-add --patch (Wincent)
 * git-prune --expire (Dscho)
 * git-add --interactive coloring (Dan Zwell)
 * whitespace error classes in diff and patch, using gitattributes (Bruce and me)
 * cvsserver runs post-receive (Michael Witten)
 * git-rebase -i gives chance to rerere (Dscho)
 * git-rebase gives more appropriate help text (Wincent)
 * make refspec matching logic in git-push and git-fetch saner (Steffen Prohaska)
 * work-tree related minor fixes (Nguyen and Dscho)
 * allow update hook to munge commit (Steven Grimm)

I'd like to explicitly exclude topics about the following, although I
think there might be worthwhile ones among them to think about in the
longer term:

 * removing dashed form from the filesystem
 * teaching diff family about fileglob pathspecs
 * making it possible to omit leading paths from diff family output when
   run from a subdirectory
