[PATCH] git-remote-hg: Fix . at end of ref

Any Mercurial tag/branch/bookmark that ended with a period would be
rejected by fast-import.  The repository could be cloned, but any
further fetch would fail.

Use a similar trick to the space handling, but only when the period is
at the end of the ref.

Probably need a more general solution to this problem.
