Funny you should say that. After spending another futile hour wading through crazy suggestions that involve tools that I can't find or don't trust, and refusing to install the full Python runtime for other utilities ... I think I'll just commit the current source directly into fresh git repos without all the history and branches. I'll move the local copies of the old Mercurial repos into an archive folder where I can refer to the history if necessary. So basically, I give up and I'm taking the dumb blunt way out. The whole version control ecosystem is like the playground of asylum inmates. *GK*
