Fix exclude regular expressions (#117)

* Fix exclude regular expressions

the current expressions look like a typo? They require one or more literal '.'s, followed by one of any symbol, then "terraform". I reasoned that the `.+` at the start was entirely superfluous and just check for the `.terraform/`

* delete extra $'s
