Do you mean the commit that was forked to create the 7.0 branch, the
commit that was released as 7.0.0, or the current status of the 7.0
branch? In turn they'd be:

1. git merge-base master origin/release_70
2. These are stored as tags I believe, though the format has changed
and we only started recently. "git tag" lists what we have now, with
an obvious mapping to releases (for a human).
3. Just plain origin/release_70

For now, svn revisions are stored in notes attached to each git
commit. Annoyingly they're not downloaded by default so you have to
run this once:

$ git fetch origin refs/notes/*:refs/notes/*

After that they'll come along with every "git fetch" or "git pull".
Once you have those, I personally just grep a "git log" for a revision
I'm interested in. You could package some variant of

$ git log --grep "git-svn-rev: 338839" -1

into a script pretty easily though.

Cheers.

Tim.
