Don't try to get text width for the null font instance, mswindows 2008-07-10 Aidan Kehoe <kehoea@parhasard.net> * redisplay-msw.c (mswindows_text_width_single_run): Explicitly check for the null font instance, and return zero if so. Avoids the crash documented in http://mid.gmane.org/18473.32468.712317.149457@parhasard.net .
