It is a different story if the fix is a good one, or has room for
improvement.  For example, the sed script that knows what is on the first
and second line and relies on that knowledge to use 1c...2c... looked very
fragile to me.

However, at least to me, this looked like an attempt for a pure "fix".

If you tell filter-branch to filter a branch A and a tag T, as the command
is advertised to rewrite positive refs that were given from the command
line, isn't it natural to expect that the command would attempt its best
effort to rewrite such a tag object?
