Three issues from a Subversion-to-git migration

I joined the git list a few hours ago because of experiences I had while migrating one of my projects, GPSD, from Subversion to git. GPSD haa a logical but unusual use case for distributed version control; the best places to test GPS sensors are out-of-doors in cars and other places where wire-line Internet is absent and one may well be out of range of a WAP.

In the course of the migration, I encountered three issues which I think could be addressed with a relatively small amount of work.

1. The git hook scripts for CIA.vc are broken (in a way that is,
fortunately, easy to fix) and generally seem to be in an unmaintained,
dusty state.

2. The git-svn migration logic does not handle unmodified SVN tag
trees well.

3. I'm prone to typos, so I quickly noticed that the existing
facilities for editing comments in commits (before they're pushed)
are clumsy and dangerous.

I will address these points in detail in separate mails. Issues 1 and 3 I can fix with working code.
