In Python, you can pass flags to regular expressions. There are two ways to do so: by passing the flag as a
flagargument to whatever regex function you're using, or by embedding the flag in the regex itself. If the flag is embedded in the regex, it is ambiguous unless it is at the start of the expression, and in Python 3.6 this is now deprecated.This pull request pulls all flags out of regexes and passes them via the
flagargument, instead. This is clearer and more consistent.
