Yes, that is a very good idea. I was wondering what would happen with that "must-not-unset-nor-smudge if it already is set" thing. > diff --git a/t/t7800-difftool.sh b/t/t7800-difftool.sh > index 42a2929..fa43c24 100755 > --- a/t/t7800-difftool.sh > +++ b/t/t7800-difftool.sh > @@ -412,6 +412,22 @@ run_dir_diff_test 'difftool --dir-diff from > subdirectory' ' > ) > ' > > +run_dir_diff_test 'difftool --dir-diff from subdirectory with GIT_DIR set' ' > + ( > + GIT_DIR=$(pwd)/.git && > + export GIT_DIR && > + GIT_WORK_TREE=$(pwd) && > + export GIT_WORK_TREE && > + cd sub && > + git difftool --dir-diff $symlinks --extcmd ls \ > + branch -- sub >output && > + sane_unset GIT_WORK_TREE && > + sane_unset GIT_DIR && It is not wrong per-se, but as you are in a subshell, you do not have to unset these, I would think. Not worth a reroll, but unless I am overlooking something (in which case please holler) I'm inclined to remove these two lines myself while queuing the series.
