Revision 1.10, Wed Jun 14 22:51:25 2017 UTC (6 years, 11 months ago) by schwarze
Branch: MAIN
Changes since 1.9: +2 -1 lines
Naive implementation of the roff(7) .po (page offset) request.
This clearly works when .po is called on the top level, but might
not be sophisticated enough if people call .po inside indentation-changing
contexts, but i haven't seen that in manual pages (yet :).
