[PATCH v4 0/4] unpack_trees_options: free messages when done

This is v4 of my series for taking care of the memory allocated by
`setup_unpack_trees_porcelain()`. As before, this is based on
bp/merge-rename-config.

would become:

  msgs[ERROR_WOULD_OVERWRITE] = msgs[ERROR_NOUPTODATE_FILE] =
        string_list_appendf(&opts->msgs_to_free, msg, cmd, cmd)->string;

I don't know if that's worth it or not (I suspect that there are other
places where appendf would be handy, but I didn't poke around).

I'll look into this over the weekend. Thanks for the suggestion.

The difference to v3 is indeed the new patch 3/4, which introduces
`string_list_appendf()`. I think that makes patch 4/4 clearer and the
resulting code less surprising.

There is an obvious candidate for using this new function in bisect.c,
but I refrained from doing that conversion in this series. While
converting that user to use this new function would be trivial and safe,
such a change might not look entirely sane on its own. The reason is
that the user does the whole `strdup_strings`-dance that I did in v3.

I think it would be much better to do that conversion as a part of a
"let's not play with strdup_strings"-patch. I have one prepared and it
looks quite ok to me. I should be able to be able to collect more
`strdup_string`-cleanups soonish and submit a series later (say, when/if
this here series has matured).

  merge-recursive: provide pair of `unpack_trees_{start,finish}()`

Martin Ågren (3):
  merge: setup `opts` later in `checkout_fast_forward()`
  string-list: provide `string_list_appendf()`
  unpack_trees_options: free messages when done
