Underlining doesn't end when it surrounds a capitalized word followed by a colon
I ran in to this on purpose by accident, and after trying a bunch of variations think I've narrowed it down to the simplest formula (see bottom)
__Frederick:__ hello
And this is what you get: Capitalized word followed by colon:
Frederick: hello ( broken)
lowercase word, followed by colon:
frederick: hello (OK)
Capitalized word followed by SEMIcolon:
Frederick; hello (OK)
iNVERTED capitalization, followed by colon:
fREDERICK: hello ( broken)
ALL CAPS, followed by colon:
FREDERICK: hello ( broken)
A single capital letter, followed by colon:
F: hello (OK)
AA pair of capitals, followed by a colon:
FR: hello ( broken)
SomthingAlmostButNOTQuiteWikiWord (followed by colon):
WhatIsFCKeditor: hello ( broken)
So.... it looks like any sequence of at least 2 letters followed by a colon, containing one or more capitals, and surrounded directly by underscore markup, will fail to end the underlining. This problem has been demonstrated in 1.5.2, 1.5.8, and now 1.6.0.
