Merge branch 'master' of git://repo.or.cz/git-gui

* 'master' of git://repo.or.cz/git-gui:
  git-gui: Use vi-like keys in merge dialog
  git-gui: Include commit id/subject in merge choices
  git-gui: Show all possible branches for merge
  git-gui: Move merge support into a namespace
  git-gui: Allow vi keys to scroll the diff/blame regions
  git-gui: Move console procs into their own namespace
  git-gui: Refactor into multiple files to save my sanity
  git-gui: Track our own embedded values and rebuild when they change
  git-gui: Refactor to use our git proc more often
  git-gui: Use option database defaults to set the font
  git-gui: Cleanup common font handling for font_ui
  git-gui: Correct line wrapping for too many branch message
  git-gui: Warn users before making an octopus merge
  git-gui: Include the subject in the status bar after commit

Also perform an evil merge change to update Git's main Makefile to
pass the proper options down into git-gui now that it depends on
reasonable values for 'sharedir' and 'TCL_PATH'.
