Thanks.

I think (1) the solution (almost) makes sense, (2) the patch needs to be
explained a lot better as you mentioned in your two messages, and (3) if
it does not affect any other case than when you are in a subdirectory of
the .git/ directory, then you are doing something funny anyway and
performance issue Dscho mentions, if any, is not a concern.

My "(almost)" in (1) above is because the patch uses this new behaviour
even when you are inside the .git/ directory itself (or at the root of a
bare repository), which is a very common case that we do not have to nor
want to change the behaviour.  It also invalidates the precondition of (3)
above.

Dscho, what performance issues do you have in mind, by the way?
