Subject: [PATCH] diff: parse ws-error-highlight option more strictly
Date: Sat, 11 Jul 2015 14:58:21 +0200	[thread overview]
Message-ID: <55A112ED.3090004@web.de> (raw)

Check if a matched token is followed by a delimiter before advancing the
pointer arg.  This avoids accepting composite words like "allnew" or
"defaultcontext".
