Revision 1.50, Sat Jan 1 12:59:17 2011 UTC (11 years, 11 months ago) by kristaps
Branch: MAIN
CVS Tags: VERSION_1_10_9
Changes since 1.49: +6 -2 lines

Add -man support for tables.  Like -mdoc, this consists of an
external-facing function man_addspan() (this required shuffling around
the descope routine) and hooks elsewhere.

Also fixed mdoc.c's post-validation of tables.
