Changes from v1:
* Dropped some changes that were independently fixed[1]
* No longer separate the f strings to their own patch
* Use r strings when the value is a regular expression
* Updated verification script
In retrospect a script to find the instances and apply fixes isn't that
useful for review, so the attached script this time just looks for
differences in the AST. Apply the series and run the script, with
the two references to compare as arguments.
There are some intentional changes to the AST now though, as the r strings
turn '\t' from a single character tab into a backslash and 't' character
pair (similar for '\n'). This does not affect the correctness of the
regular expression though.
