From 69bcb1f3b2065231849af71fbec2505aad407012 Mon Sep 17 00:00:00 2001 From: Kevin Ryde Date: Sat, 26 Dec 2009 22:00:47 +0000 Subject: [PATCH] (Man-bgproc-sentinel): When "-k foo" produces no output show error "no matches" rather than "Can't find manpage", as the latter reads like -k was interpreted as a page name, which is not so.
