Log Message:
Import Regexp-Trie-0.02 as devel/p5-Regexp-Trie.

Regexp::Trie is a faster but simpler version of Regexp::Assemble or
Regexp::Optimizer. It builds a trie-ized regexp as above.

This module is faster than Regexp::Assemble but you can only add literals.
a+b is treated as a\+b, not "more than one a's followed by b".
