[FWP] string evenness

[Jeff Pinyan <jeffp@crusoe.net>]

>From a CLPM challenge/request, I give you this:

  $half = int(length($str)/2);
  $str =~ s{( ?)([^ ]*)(?<=^.{$half})([^ ]*)( ?)}
           { length($2) < length($3) ? "\n$2$3$4" : "$1$2$3\n" }e;

It turns the ' ' nearest the center of the string into a newline.  This is
used for making things like

  extraterrestrial space monkeys

into

  extraterrestrial
  space monkeys
