Request: remove whitespaces at the beginning and end of each line

[uwidev]

So like an option to join all lines together with a space?

e.g.

a, 
b, 
c

Now becomes?

a, b, c

@uwidev Sorry if I wasn't clear enough I just want the trailing and 'leading' whitespace to be removed e.g.

 abc 
should be
abc
