Revision 1.16, Sat Jan 5 00:36:50 2019 UTC (5 years, 8 months ago) by schwarze
Branch: MAIN
CVS Tags: VERSION_1_14_5 Changes since 1.15: +3 -2 lines
Some high-level block macros have an effect similar to temporarily
suspending no-fill mode during their head. Model this with an
additional roff parser state flag ROFF_NONOFILL. That is much
simpler than it would be to save and restore the ROFF_NOFILL flag
itself, in particular since the latter can be switched (with lasting
effect) by the .nf and .fi requests even while its effect is
temporarily suspended.
This commit does not change formatting yet, but prepares for future
formatting simplifications and improvements.
