implemented the ^~ pattern match construct: the rest of the pattern will be an Advanced Regular Expression
* Allows searching by regular expressions.
We will never support all ARE constructs in TECO patterns, so this is useful to have available.
* Can only be typed upcaret.
This leaves ^E~q available as an escape-regexp string building construct.
* Once we replace the pattern2regexp converter with a custom terex lexer,
we might want to restrict ^~ to the beginning of the pattern.
Currently, however it can be anywhere, so you can mix TECO patterns with regular expressions.
