When collaborating with projects managed by some other
scm, it often makes sense to have git read that other
scm's ignore-files. This patch lets git do just that, if
the user only tells it the name of the per-directory
ignore file by specifying the newly introduced git config
option 'core.ignorefile'.
Theoretically, this could cause problems when projects get
ported from some other scm to git, but in practice that
is a moot point, as such changes are always followed by a
flagday anyway.
