Re: [PATCH v3 2/5] fetch: use strbuf to format FETCH_HEAD updates

This commit refactors `append_fetch_head()` to use a `struct strbuf` for
formatting the update which we're about to append to the FETCH_HEAD
file. While the refactoring doesn't have much of a benefit right now, it
servers as a preparatory step to implement atomic fetches where we need

s/servers/serves/

to buffer all updates to FETCH_HEAD and only flush them out if all
reference updates succeeded.
