Revision 1.53, Wed Mar 22 07:16:54 2017 UTC (7 years, 2 months ago) by nicm
Branch: MAIN
CVS Tags: OPENBSD_6_1_BASE, OPENBSD_6_1
Changes since 1.52: +2 -1 lines
Add support for the strikethrough attribute (SGR 9), using the new smxx
terminfo capability. This means there are now nine attribute bits, so
anything above 0xff uses an extended cell.
