Revised candidate for perlrequick.pod

Here is the revised candidate for perlrequick.pod, a quick start guide
for Perl regexps.  The patch against the original is below, or if you
would rather download the new version, it can be found at

I'd like to thank Brad Hughes and Ilya Zakharevich for helpful comments.

  Regexps must match a part of the string I<exactly> in order for the

  Character classes are denoted by brackets C<[...]>, with the set of

  In the last statement, even though C<'c'> is the first character in
  the class, the earliest point at which the regexp can match is C<'a'>.
