Cannot resolve $git_dirty inside of $GIT_DIR

[eacousineau]

find_git_dir() does not play nicely inside of $GIT_DIR, hence the error message checking.
A possible solution would be to resolve the proper work tree directory. Not sure how to do that with the plumbing / porcelain stuff (realized I should have said "plumbing" in that first commit haha). Trying out the "root" alias trick did not seem to work either.

When you say $GIT_DIR, do you mean the .git folder inside of a working directory? If not, sorry for my stupidity. If yes, then I'm not sure it's a huge deal, git status doesn't work inside of it either :)

[eacousineau]

Yeah, that was what I meant, so no need for apologies haha. I agree that it isn't a huge deal (now that it seems hard to implement :P).

Well, only thing I can think of is checking if the output from pwd for example contains /.git, and then attempt run git status against the parent directory of the .git directory. I might give it a shot just for fun, and if it doesn't slow down the find_git_dirty function in any noticeable way I'll push it :)
