Hi,

Enclosed is a patch to de-backspace Nm/Nd lines for mandocdb(8).  This 
arose from seeing the results for some LAPACK manuals, which are 
notoriously shitty.  It also cleans up handling of the non-terminated 
string a bit and adds a quick check to see if SYNOPSIS has been reached 
right after the NAME.  This occurs when manuals look like this:

  NAME
  SYNOPSIS
    Blah blah blah

Again, LAPACK...

If it's relevant, a check for NAME could also occur, then loop back into 
the fgets().  Thoughts?

This area still needs a bit more attention to handle situations like:

  foo -[\n]?
  [whitespace]foo - bar[whitespace][\n]?

I need to check this over a bit more carefully to see if I'm not 
trampling past the array, but this is a start.

Best,

Kristaps
