I do this sort of digging fairly often.

I am not going to do this particular one myself, but the general procedure
is to first run "git log --diff-filter=A strbuf.[ch] parse-options.[ch]"
to find which commits introduced them (hence, learn who did it, when and
why), then go back to the list archive to find the discussions that lead
to these changes.
