Remove unnecessary empty lines in article body. New feature?

Hello,

when reading news some articles contains (in my opinion) unnecessary  
empty lines which bothers me. Those lines are:

-leading empty lines (the first non empty line jumps from article to  
article)
-multiple empty lines whithin the body
-trailing empty lines (annoying when page-down one page and the next  
page is blank)

So I patched my tin to behave like this:

-remove leading empty lines
-replace multiple empty lines with one empty line (when not in  
verbatim blocks)
-remove trailing empty lines (keep one if an attachement follows)

Empty lines in this context are lines with a length of 1 (line[0] ==  
'\n'). For details see the patch attached.

If anyone else is interested in this feature I would make it a 'M'enu  
option (for instance: "Trim article body", default OFF).

Regards,
Dennis
