[PATCHv4 0/5] git-gui: more robust handling of fancy repos

A re-issue of the patchest to make git-gui more robust towards non-standard repository setup, with two additional fixes.

The first three patches are unchanged from the previous iteration (still waiting for review, actually).

The 4th sets GIT_DIR and GIT_WORK_TREE in git-gui to ensure that all external tool invocation work in the same setup.

The last one also updates the shortcut library to make use of _gitworktree instead of the old assumption that the worktree is the updir of the git dir. I can't really test this patch though because I don't have Windows.

Giuseppe Bilotta (5):
  git-gui: handle non-standard worktree locations
  git-gui: handle bare repos correctly
  git-gui: work from the .git dir
  git-gui: set GIT_DIR and GIT_WORK_TREE after setup
  git-gui: update shortcut tools to use _gitworktree
