Revision 1.2, Sun Apr 24 13:38:48 2022 UTC (2 years, 1 month ago) by schwarze
If a .shift request has a negative argument, do not use a negative array index but use 0 instead of the argument, just like groff. Warn about the invalid argument. While here, fix the column number in another warning message. Segfault reported by tb@, found with afl(1). |
