Return to libmandoc.h CVS log

Up to [cvsweb.bsd.lv] / mandoc

Squash bug noted by Ulrich Spoerlein where "-" were being converted to
ASCII_HYPH, as per normal, but were screwing up mandoc_special().  Fixed
by making mandoc_special() first check isspace() instead of ! isgraph(),
then normalise its string as it passes out.  This require de-constifying
some validation routines not already de-constified (those in libman),
but that's ok, because I'd like to be pushing actions into validation
routines to save on space and redundant calculations.
