--- Comment #22 from Bartosz gang65@poczta.onet.pl --- Thanks for link. It is very interesting, and allow me to make much more tests which check current :BreakLine function in Windows.
I checked colons, semicolons, dots and brackets, and for Windows XP implementation of the BreakLine functions it is treated as standard characters. I haven't observed any special behavior.
I will continue testing. If I find any uncovered case, I will fix that and add tests case.
