In git-check-ref-format (1), there is the following rule for refnames:
3. It cannot have ASCII control character (i.e. bytes
whose values are lower than \040, or \177 DEL), space,
tilde ~, caret ^, colon :, question-mark ?, asterisk *,
or open bracket [ anywhere;
and indeed, this rule is enforced by "git fast-import". hg-fast-export
already checked for all of the visible characters listed except for ~
and converted them to underscores. For some reason the tilde was
forgotten. This patch makes good on the omission.
Note that control characters are still left alone.

At least the opensolaris hg repo has tag names containing '*',
so sanitize all branch and tag names roughly according to the
specs for git-check-ref-format(1).

Merges were completely broken as they ended up with twice the same
parent in git. Still everything besides gitk seemed to work.
This because of 1) the incorrect assumption that a commit's parent is
the commit exported right before it and 2) some confusion with markes
being saved/loaded/used since git-fast-import doesn't allow for a ":0"
mark to map hg revision 1:1 to marks.
The merge "algorithm" now works like this:
1) If the commit's higher parent (highest hg rev), is not the last
commit exported for a particular branch, we issue a "from" command to
place it on top of it.
2) If the commit's lower parent exists, we issue a "merge" for it.
This is much simpler and seems to produce correct merges in git. And
while I'm at it, make output less confusing by prepending the target
branch name to each line.
The "twice the same parent" bug was discovered by Michele Ballabio on
the git list.

Unfortunately, I can't do 'import hg-fast-export' from python itself, so
we need to move some common methods into 'hg2git.py' which is to be used
as a library for common hg->git routines.
