Subject: format_trailer_info(): move "fast path" to caller
X-Git-Tag: v2.45.0-rc0~113^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2c948a78fd449a03c114802772acd4abfec25bba;p=thirdparty%2Fgit.git

format_trailer_info(): move "fast path" to caller

This is another preparatory refactor to unify the trailer formatters.

This allows us to drop the "msg" parameter from format_trailer_info(),
so that it take 3 parameters, similar to format_trailers() which also
takes 3 parameters:

    void format_trailers(const struct process_trailer_options *opts,
                         struct list_head *trailers,
                         struct strbuf *out)

The short-term goal is to make format_trailer_info() be smart enough to
deprecate format_trailers(). And then ultimately we will rename
format_trailer_info() to format_trailers().
