Revision 1.1, Fri Aug 24 23:12:35 2018 UTC (5 years, 9 months ago) by schwarze
Branch: MAIN
CVS Tags: VERSION_1_14_6, VERSION_1_14_5, HEAD

Rudimentary implementation of the roff(7) .while request.
Needed for example by groff_hdtbl(7).

There are two limitations:
It does not support nested .while requests yet,
and each .while loop must start and end in the same scope.

The roff_parseln() return codes are now more flexible
and allow OR'ing options.
