Revision 1.10, Mon Mar 16 22:19:19 2009 UTC (15 years, 3 months ago) by kristaps
Branch: MAIN
Changes since 1.9: +1 -85 lines
Fixed mdoc_phrase escape handling.
Added MDOC_IGNDELIM (Pf, soon Li, etc.).
macro_constant_delimited ignargs -> argv.c parsing.
Renamed macro functions to correspond to ontologies.
`Fo' and `St' made callable (compat documented).
strings.sh deprecated (directly using CPP).
Abstracted ASCII translation into ascii.{c,in}.
ASCII table uses a self-reordering chained hashtable.
Removed old regressions.
