[BACK]Return to libman.h CVS log [TXT][DIR] Up to [cvsweb.bsd.lv] / mandoc

File: [cvsweb.bsd.lv] / mandoc / libman.h (download)

Revision 1.67, Sun Dec 28 14:42:27 2014 UTC (5 years, 10 months ago) by schwarze
Branch: MAIN
CVS Tags: VERSION_1_13_3
Changes since 1.66: +2 -1 lines

mdoc(7) already uses the mandoc(1) -Ios argument in the footer line
when .Os has no argument, so do the same for man(7) when .TH has less
than four arguments; there is no reason to treat both differently.
Issue found following a question from Thomas Klausner <wiz at NetBSD>.
