From 3bb55e8aa86f054c081c372b227f723e3aad14c7 Mon Sep 17 00:00:00 2001 From: Brian Gesiak Date: Wed, 30 Apr 2014 17:58:06 +0900 Subject: strbuf: use _rtrim and _ltrim in strbuf_trim strbuf_trim() strips whitespace from the end, then the beginning of a strbuf. Those operations are duplicated in strbuf_rtrim() and strbuf_ltrim(). Replace strbuf_trim() implementation with calls to strbuf_rtrim(), then strbuf_ltrim().
