Revision 1.2, Fri Dec 14 06:33:14 2018 UTC (19 months, 3 weeks ago) by schwarze
Branch: MAIN
CVS Tags: VERSION_1_14_5, HEAD
Changes since 1.1: +1 -2 lines

Cleanup, no functional change:
Now that message handling is properly encapsulated,
remove struct mparse pointers from four structs (roff, roff_man,
tbl_node, eqn_node) and from the argument lists of five functions
(roff_alloc, roff_man_alloc, mandoc_getarg, tbl_alloc, eqn_alloc).
Except for being passed to the main program as an opaque object,
it now only occurs in read.c, as it should, and not across 15 files
like in the past.
