#47 problem with graph smileys

[Henning Schaefer]

Graphical smileys do only work if there is at least
one blank between the text and the smiley, or a blank
between two different smileys (example: "Gotta get
some :coffee:" will work, "some:coffee:" won't work
(but has worked in 14.5)). Don't know, is it "not a
bug but a feature"? Actually, my users keep on
complaining about that ;)
