b21680baf5391a602b295b9d7d0ef66553661cb9 test/contrib: Fix invalid escapes in regex strings (Ben Woosley)

Pull request description:

  This is a second go at #15221, fixing new lints in:
  W504 line break after binary operator
  W605 invalid escape sequence
  F841 local variable 'e' is assigned to but never used

  This time around:
  * One commit per rule, for easier review
  * I went with the PEP-8 style of breaking before binary operators
  * I looked into the raw regex newline issue, and found that raw strings with newlines embedded do work appropriately. E.g. run `re.match(r" \n ", " \n ")` to check this for yourself. `re.MULTILINE` exists to modify `^` and `$` in multiline scenarios, but  all of these searches are per-line.
