Agreed.  It's perfectly possible for the branch to have changed between the
magic revision and HEAD.  When editing STATUS, the base revision (argument to
the -r option) should be HEAD resolved to a number.

Something like this, perhaps?

[[[
release.py create-tag: Fix an out-of-date error when the branch has changed
after the magic revision.

* tools/dist/release.py
  (create_tag): Use HEAD rather than the magic revision as the base revision
    for the "Post-release housekeeping" commit.
