Diff since v4:

* Remove commits that may have compatibility issues
* Fix the problems that mentioned in v4
* Use OPT_STRING_LIST instead of OPT_CALLBACK_F to parse multiple "-m"

Thanks.

    @@ Commit message
         needed, but actually when inserting, "strbuf_insertstr(&d.buf, 0,
         "\n");" will do the "grow" for us.
     
    +    Best guess may be that the author originally inserted "\n" manually by
    +    direct manipulation of the strbuf rather than employing a strbuf
    +    function, but then switched to strbuf_insert() before submitting the
    +    series and forgot to remove the now-unnecessary strbuf_grow().
