Revision 1.185, Thu Sep 23 20:40:00 2010 UTC (14 years ago) by schwarze
Branch: MAIN
Changes since 1.184: +13 -7 lines
When the HEAD of an .Nm block in the SYNOPSIS might be wider
than the column containing it, the TERMP_HANG flag is required,
but avoid the flag when we know that the HEAD is shorter,
because in that case, the flag might ruin the alignment.
Problem originally reported by jmc@, who also spotted a regression
in an earlier version of this patch.
