Fix invalid escape sequences (regular expressions)

[pfuntner]

In #118 I created a script to find scripts that might have invalid escape sequences - that have regular expression escape sequences. and either need to be expressed in raw-strings or with the backslashes escaped.

Here's a list of such scripts in the repo but since the repo is such a hodge-podge, I might not use them all anymore:
