Subject: [PATCH v2 10/12] diffcore-pickaxe: Add regcomp_or_die()
Date: Sat, 25 Jun 2016 07:22:36 +0200 [thread overview]
Message-ID: <20160625052238.13615-11-pclouds@gmail.com> (raw)
In-Reply-To: <20160625052238.13615-1-pclouds@gmail.com>
There's another regcomp code block coming in this function that needs
the same error handling. This function can help avoid duplicating
error handling code.
