From 2e2bbb9624e10537560c3ac45ff6820ff773b3d6 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Wed, 26 Apr 2017 23:27:17 -0400 Subject: am: simplify allocations in get_commit_info() After we call split_ident_line(), we have several begin/end pairs for various parts of the ident. We then copy each into a strbuf to create a single string, and then detach that string. We can instead skip the strbuf entirely and just duplicate the strings directly. This is shorter, and it makes it more obvious that we are not leaking the strbuf (we were not before, because every code path either died or hit a strbuf_detach).
