Subject: Indenting strings - elegant alternatives?

Just in case someone would like to contribute ideas of elegant code:

PROBLEM:

Given a string of lines (for example, "abc\nde\nfgh\n") and a number n, 
produce a string of the same lines, but each line indented by n spaces.
If the original string does NOT end in \n, it is OK (but not required)
to have it ending in \n in the result.

Speed is not an issue; I'm mainly looking EITHER for compact/elegant 
code in Core Ruby (noing well that elegance is a very subjective 
criterium), OR for some library function which already has solved this.

Here is my own (pretty straightforward) solution to the problem:

def indent(n,s)
  (s.split.map {|x| (' '*n)+x}.join("\n"))+"\n"
end

This works, so the only reason I'm posting this, is to learn about
alternative ways of doing this.
