Hm, that's weird. There should be no reason for the conversion to push new SHA1s for the same commit (if the conversion doesn't change, anyway). I'll try to look into it.
 
If git should be wikimedia VCS of choice, head/master should be maintained in git.
We are in the middle of converting, so this is not a reasonable thing to ask. We *will* maintain in git, but *for now* (until the 26th, if everything is done by then) we still have SVN as master and git as mirror.

I haven't tested it, but it seems reasonable, that every operation of svn2git crate new hashtags of commits in git and from point of view of git repository they aren't identical, so merging that repository make mess in history of commits.
Running the conversion twice should never give different SHA1s for the same commit, unless something changes in the conversion code.
