Revision 1.8, Tue Mar 2 00:38:59 2010 UTC (14 years, 3 months ago) by schwarze
Branch: MAIN
CVS Tags: OPENBSD_4_7_BASE, OPENBSD_4_7
Changes since 1.7: +2 -1 lines
Proper inter-sentence spacing for mdoc(7).
When a text line or a non-block macro line in the source code ends
in any of ".!?", consider that an end of sentence (EOS).
This makes Jason's rule "new sentence, new line" even more important.
Let the parser detect the EOS and insert a token into the AST.
Let the -Tascii frontend render the EOS token as a double space before
the next word.
