It's likely I misunderstood what you're trying to do. If you have
some work in progress, I'd be glad to look at it.
Anyway, concerning tag fixup branches: git://repo.or.cz/cvs2svn.git
has an example in cvs2svn_lib/git_output_option.py::process_tag_commit.
The idea is to make commits that don't belong to any branch on a
separate TAG_FIXUP ref, using the "reset" command where appropriate;
then the resulting commits can be inspected, merged, reset to, or used
in some other way later.
The "tag fixup" idea is that in VCSes like CVS, tags do not
necessarily match the content on any branch. So the history looks
somewhat like so (time flowing left to right):
TAG
/
o --- o --- o --- o --- o --- o ...
instead of the perhaps more sensible
o --- o --- o --- TAG --- o --- o ...
The side branch leading up to a tag does not correspond to any branch
name; after it is in the correct state one can use the "tag" command
to get it remembered in permanent history. The same technique might
be useful whenever you are creating history that is not meant to stay
permanently on any branch.
