Hi,

"git diff" ignores the GIT_EXTERNAL_DIFF variable in a particular situation:
when there are conflicts after "git stash apply".

To reproduce:
  - Set environment variable GIT_EXTERNAL_DIFF to point to the attached
    script.
  - Make a clean gnulib checkout, 1 day old.
  - Add a entry to the top of the ChangeLog.
  - $ git pull
    fails due a conflict.
  - $ git stash
  - $ git pull
  - $ git stash apply
  - $ git-diff | cat
    yields:
diff --cc ChangeLog

The script has not been called (witness: the echo command at its line 2).

Can it be called, like in the case of "git-diff --cached"?
