wxWidgets/tests/controls/textctrltest.cpp
Vadim Zeitlin efc2a9da2d Fix pasting long strings in wxTextCtrl under MSW 
Adjust the length limit before pasting to ensure that all text on
clipboard will be successfully pasted, instead of only pasting the part
of it which fits.

Add a unit test checking that this works.

Closes #4646.
