I'd say yes.

It is utterly _inconvenient_ to have to cd to the working tree when you 
just want to check the status, for example.  And git already knows about 
the work-tree!

But you got me convinced about the relative path: it is true that nobody 
who has not set core.worktree should be affected.

So I will do something like

	if (!inside_work_tree()) {
		puts(get_git_work_tree());
		continue;
	}
	[do the old thing of outputting ../../[...]]

In fact, I had this in an unpublished version of the patch, and decided 
that I could remove more lines without breaking the test suite.

Heck, I'll even add a test case to make sure that behavior is maintained.  
Okay?

P.S.: I'll be offline for a few hours, but then come back to finish it up.
