[PATCH 0/8] make gitk work better in non-top-level directory

[Martin von Zweigbergk <martin.von.zweigbergk@gmail.com>]

This series fixes a few different bugs in gitk related to its working
directory.

I started working on patch 1, which fixes "Highlight this only/too"
when gitk is started in a subdirectory. This problem has bothered me
for a long time, but I had heard that the Tcl code in gitk was hard to
maintain, so I didn't have a look at it until now. I have to say that
it was a lot easier to follow the code than I had feared.

While testing that the fix in patch 1 worked, I found that gitk does
not work very well when the work tree is not at ".git/..", so most of
the other patches try to improve that situation.

I think I have tested most combinations of setups (top-level dir,
subdir, separate work tree, bare repo, .git) and operations (highlight
file, blame, external diff, show origin of line).


Martin von Zweigbergk (8):
  gitk: fix file highlight when run in subdirectory
  gitk: fix "show origin of this line" with separate work tree
  gitk: fix "blame parent commit" with separate work tree
  gitk: fix "External diff" with separate work tree
  gitk: put temporary directory inside .git
  gitk: run 'git rev-parse --git-dir' only once
  gitk: simplify calculation of gitdir
  gitk: show modified files with separate work tree
