From 31471ba21ee29886ab856981e52f723c913d7f40 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Thu, 21 Jul 2016 18:46:44 +0200 Subject: strbuf: avoid calling strbuf_grow() twice in 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.
