annotate lisp/term/bg-mouse.el @ 5295:2474dce7304e
Make sure (format "%b" 0) is non-zero length, print.c
src/ChangeLog addition:
2010-10-25 Aidan Kehoe <kehoea@parhasard.net>
* print.c (ulong_to_bit_string): If printing zero, actually print
a zero, don't return the empty string.
tests/ChangeLog addition:
2010-10-25 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Test format strings with %b, too.
