[conspire] URL sanity

'http://ncpa.n0ary.org/ncpabandplan.html' is a page.
'http://ncpa.n0ary.org/ncpabandplan.html.' is not a page.

There's a good reason why I put space characters between URIs and
adjoining punctuation, during normal mentions in plaintext, like 
https://www.youtube.com/watch?v=B_bOebWQoRc .  Doing so automatically 
averts an ambiguity problem that otherwise exists for the reader.

Some folks enclose mentioned URIs in angle brackets.  Far too fiddly 
and ugly, IMO.

(URL above is the legendary New Year's Eve 1977 Covent Garden live
performance of 'Die Fledermaus'.  Stick with it even though the first
14 minutes have an annoying warble.  It's worth it.)
