From ba891d68b4ff17faaea3d3a8bfd82af3eed0a134 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Fri, 27 Jul 2018 08:22:04 +0200 Subject: qstring: Move qstring_from_substr()'s @end one to the right qstring_from_substr() takes the index of the substring's first and last character. qstring_from_substr(s, 0, SIZE_MAX) denotes an empty substring. Awkward. Shift the end index one to the right. This simplifies both qstring_from_substr() and its callers.
