Subject: [PATCH v2 8/9] diffcore-pickaxe: "share" regex error handling code
Date: Wed,  8 Jul 2015 17:38:38 +0700	[thread overview]
Message-ID: <1436351919-2520-9-git-send-email-pclouds@gmail.com> (raw)
In-Reply-To: <1436351919-2520-1-git-send-email-pclouds@gmail.com>

There's another regcomp code block coming in this function. By moving
the error handling code out of this block, we don't have to add the
same error handling code in the new block.
