Subject: Parse and ignore .IX (generate index entry) macros because pod2man(1)
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=f69f4bab0b601652be0766c00aea4e9a8b96aac1;p=openbsd

Parse and ignore .IX (generate index entry) macros because pod2man(1)
emits them, by default without defining them, relying on the roff(7)
quirk that undefined macros have no effect.
This cures 1996 mandoc ERRORs in src/gnu.
