Subject: strbuf: add fixed-length version of add_wrapped_text
X-Git-Tag: v1.7.5-rc0~59^2~2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=98acc837a14c2ab1975b38b93cb028e87e47ad4a;p=git.git

strbuf: add fixed-length version of add_wrapped_text

The function strbuf_add_wrapped_text takes a NUL-terminated
string. This makes it annoying to wrap strings we have as a
pointer and a length.

Refactoring strbuf_add_wrapped_text and all of its
sub-functions to handle fixed-length strings turned out to
be really ugly. So this implementation is lame; it just
strdups the text and operates on the NUL-terminated version.
This should be fine as the strings we are wrapping are
generally pretty short.  If it becomes a problem, we can
optimize later.
