 [[plugins/map]] (and I) could benefit from a bonus parameter:
 
-	else="Display this if no page matches the [[ikiwiki/PageSpec]]"
+	else="Display this if no page matches the PageSpec"
 
 This was quite simple, so I implemented this (branch "map" in my
 ikiwiki repo, see my user page for the up-to-date URL). Not patched the
 documentation yet, I'm waiting for feedback first, but I'll do it for sure. -- [[intrigeri]]
