[Bug 32126] Mathcad 14 ends up in a loop, needs IMLangLineBreakConsole::BreakLineA/W implementation

--- Comment #21 from Nikolay Sivov  ---
I meant a generic line breaking algorithm as described here
http://unicode.org/reports/tr14/. We already have that implemented in usp10 and
dwrite; unicode.org provides test data for it in LineBreakTest.txt file, if
you're interested you can pick some interesting cases from it and see if
BreakLine behaves accordingly or not.
