Changes 1.7.6:
* Various git-svn updates.
* Updates the way content tags are handled in gitweb.  Also adds
  a UI to choose common timezone for displaying the dates.
* Similar to branch names, tagnames that begin with "-" are now
  disallowed.
* Clean-up of the C part of i18n (but not l10n---please wait)
  continues.
* The scripting part of the codebase is getting prepared for i18n/l10n.
* Pushing and pulling from a repository with large number of refs that
  point to identical commits are optimized by not listing the same commit
  during the common ancestor negotiation exchange with the other side.
* Adding a file larger than core.bigfilethreshold (defaults to 1/2 Gig)
  using "git add" will send the contents straight to a packfile without
  having to hold it and its compressed representation both at the same
  time in memory.
* Processes spawned by "[alias] <name> = !process" in the \ 
configuration
  can inspect GIT_PREFIX environment variable to learn where in the
  working tree the original command was invoked.
* A magic pathspec ":/" tells a command that limits its operation to
  the current directory when ran from a subdirectory to work on the
  entire working tree. In general, ":/path/to/file" would be relative
  to the root of the working tree hierarchy.
  After "git reset --hard; edit Makefile; cd t/", "git add \ 
-u" would
  be a no-op, but "git add -u :/" would add the updated contents of
  the Makefile at the top level. If you want to name a path in the
  current subdirectory whose unusual name begins with ":/", you can
  name it by "./:/that/path" or by "\:/that/path".
* "git blame" learned "--abbrev[=<n>]" option to \ 
control the minimum
  number of hexdigits shown for commit object names.
* "git blame" learned "--line-porcelain" that is less \ 
efficient but is
  easier to parse.
* Aborting "git commit --interactive" discards updates to the index
  made during the interactive session.
