Match IP at start of line in `disable`
Match IP at start of line in `disable`

The `disable` regular expressions avoid matching against commented lines
by excluding '#' characters at the beginning of the line. However, the
IP portion of the record is at the beginning of non-commented lines, so
in order to match these IPs the `target_regex_ip` needs to have the
search term checked against the beginning of the line. Therefore, the
`[^#]` at the beginning of `target_regex_ip` must be removed to make
`search_term` properly match these IPs.
