plines_win_nofold(): Ignore virtcols after 32000th computation #3527
Avoid crashing or hanging when editing a file than contains ludicrously
long lines (more than 100,000,000 virtual columns).
The change is in plines_win_nofold, which is called by wrapping and folding
code. As a result, wrapping and folding may be done incorrectly when the UI is
capable of rendering more than 32000 characters at a time (tiny font).
fixes #2838
