The replace function doesn't handle regexps AFAIK - you could look at
SUBSTRING() in the POSIX Regexp section of the functions reference but I
don't think that's going to do it either.

The problem is you seem to want to remove spaces after "hello" and "world" - I
think that means you need perl regexps or a loop.

Unless some posix guru steps forward, I'd say the easiest way is to build a
loop that repeatedly calls replace(my_string,' \n','\n')
