Subject: [PATCH] lib/parser: Not recognize nul string as "%s" (6/6)
Date: Tue, 07 Oct 2003 01:58:47 +0900 [thread overview]
Message-ID: <87wubinvzs.fsf@devron.myhome.or.jp> (raw)
Hi,
Current match_token recognize "foo=" as "foo=%s". So this change the
nul string does not recognize as "%s".
(Umm... this should be check by caller?)
