[Groff] End-of-line whitespace.

[Kristaps Dzonsons]

Hello,

Are there any concrete reasons for avoiding trailing eoln whitespace in 
roff files (specifically -man and/or -mdoc)?  These are stripped from 
input anyway "foo    " followed by "bar" outputs "foo bar", so I'm hard 
up for providing a reason beyond "Do It".

Thank you,

Kristaps
