Revision 1.35, Sun Dec 15 21:23:52 2013 UTC (7 years, 10 months ago) by schwarze
Branch: MAIN
CVS Tags: VERSION_1_12_3
Changes since 1.34: +2 -2 lines

The "value" argument to the roff(7) .nr requests ends right before
the first non-digit character.  While here, implement and document
an optional sign, requesting increment or decrement, as documented
in the Ossanna/Kernighan/Ritter troff manual and supported by groff.
