strbuf: avoid calling strbuf_grow() twice in strbuf_addbuf()rs/use-strbuf-addbuf
Implement strbuf_addbuf() as a normal function in order to avoid calling strbuf_grow() twice, with the second callinside strbud_add() being a no-op. This is slightly faster and also reduces the text size a bit. Signed-off-by: Rene Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
