The person who commits the changes.  As long as the changes are small
enough, they can go in with that tag.

About 15 lines, disregarding trivial ones.  If you aren't sure, please
ask.

It depends what kind of changes you did.  In general, it is better to
commit the contribution as is, with the original author, then make
your followup changes (in a separate commit) with you as the author.
