Don't add spurious empty lines.

I would have put this on a single line, even if it breaks the 80 character limit.

BTW, is breaking that limit more of a problem for you?  I can certainly
understand that you want to strictly obey it if it is..

Both of these need "export" I believe...

Thank you! I'll follow your suggestions.
Regarding the 80 chars limit - not, it's not strictly a problem, but since my 
braille device is 80 chars and I'm using a terminal 80x50 (80 colums, 50 rows), 
I felt more confortable with it. No problems, I'll add them on a single line.
