docbook2mdoc: Do not include literal linefeed characters in text nodes;

[schwarze@mandoc.bsd.lv]

Log Message:
-----------
Do not include literal linefeed characters in text nodes;
instead, let the parser split them into two text nodes.

For now, let the formatter start text nodes preceded by whitespace 
on new output lines, which is a crude way of preserving input line
breaks and making sure output text lines are limited to reasonable
length.
