[PATCH] Friendlier error message for commands that can't be run from a subdirectory.

This doesn't fix the underlying problem (those commands ought to work
from any directory) but it is at least less baffling for the common case.
It's pretty braindead -- if you for some reason have a .git directory
inside one of your subdirectories, you'll get the old error message.
