CVS commit: src/lib/libcurses

["Roy Marples" <roy%netbsd.org@localhost>]

Module Name:    src
Committed By:   roy
Date:           Fri Mar 29 16:56:58 UTC 2019

Modified Files:
        src/lib/libcurses: refresh.c

Log Message:
Use WCOL rather than wcwidth(3) as we should already know the width
during refresh.
Ensure the character width is not negative when advancing during refresh
(unlikely) and we actually have something to insert in the lower right
corner depending on terminal caps.

Fixes PR lib/54085
