Re: Problems with move_it_in_display_line_to X when tabs exist.

I built Emacs 26 for Windows (using my modification patch) and ran the same 
series of tests along with taking a screen-shot at the link below.  
it.pixel_width is correct on Emacs 26 for Windows, whereas it.pixel_width is 
wrong on Emacs 26 for OSX 10.6.8.  it.what reports IT_CHARACTER on both 
platforms, however, I expected the result to be IT_STRETCH.  Later this 
evening, I will experiment with the recipe that you tried in your previous 
email.
