These string_list instances were allocated by get_renames() and
get_unmerged for the sole use of this caller, and the function is
responsible for freeing them, not just their contents.

`old` is not used outside the loop and would get lost

This frees `ce` would be leaking in the error path.

Additionally a free is moved towards the return. This helps code
readability as we often have this pattern of freeing resources just
before return/exit and not in between the code.

There was one continue statement without an accompanying `free(ref)`.
Instead of adding that, replace all the free&&continue with a goto
just after writing the refs, where we'd do the free anyway and then
reloop.

When git_connect() is called to see how the URL is parsed for
debugging purposes with CONNECT_DIAG_URL set, the variable conn is
leaked.  At this point in the codeflow, it only has its memory and
no other resource is associated with it, so it is sufficient to
clean it up by just freeing it.

The prompt string "remove?" used when "git clean -i" asks the user
if a path should be removed was localizable, but the code always

localized.
