This task is stupid.

You should only address the "string is longer" issue, use cut (see
'man cut' if you need help), and then tell whomever is asking you to
do this that it can't be done.

(wipes hands, beams triumphantly)

I win.

Otherwise, if they insist that the "edge case" of a string shorter
than five characters needs to be lengthened (do those even exist???)
insist that their inflexibility is hurting the agility of your team,
and demand that they find budget to hire an intern.  Also, pad your
estimate with acronyms, like TDD and BUTT.

If they continue to give you flak, cough and say "anassholesayswhat."
When they say, "what?"  Laugh.

Maybe try writing this in Rails.  I'm pretty sure they have a template
tag that says ""some string of unfathomable
length".shorten_this_if_its_greater_than_five_characters_but_if_its_less_make_it_longer
 Notice that you don't have to import that (agile!) and you don't have
to use parens (agile!).

If they won't let you write it in Rails, quit.

Maybe Erlang can handle this?  I'm pretty sure conditional lengthening
/ shortening of strings is something that Functional languages do
better than procedural languages.  Paul Graham wrote an article about
it in 1992, right before he created Ebay in Lisp.

Do you use a Mac?  You should.  Because the Mac takes care of Strings.
 Automagically.
