Match-one-or-more Operator

The Match-one-or-more Operator (`+' or `\+')
--------------------------------------------

  If the syntax bit `RE_LIMITED_OPS' is set, then Regex doesn't
recognize this operator.  Otherwise, if the syntax bit `RE_BK_PLUS_QM'
isn't set, then `+' represents this operator; if it is, then `\+' does.

  This operator is similar to the match-zero-or-more operator except
that it repeats the preceding regular expression at least once; 
see Match-zero-or-more Operator., for what it operates on, how some
syntax bits affect it, and how Regex backtracks to match it.

  For example, supposing that `+' represents the match-one-or-more
operator; then `ca+r' matches, e.g., `car' and `caaaar', but not `cr'.
