apostrophe character in .cfg files

[obriencj]

The apostrophe (single-quote) character in a setup.cfg leads to all text after that point being miscolored, until a matching apostrophe is run across.

In the case of setup.cfg, the apostrophe character has no special meaning, and should not trigger any sort of coloration at all. This is from using Python's ConfigParser underlying implementation.

I run into this all of the time because my last name has an apostrophe in it. eg.
https://github.com/obriencj/koji-smoky-dingo/blob/master/setup.cfg

In the cases for this type of file, an apostrophe may have meaning as part of the value to be parsed later on, eg. these lines

install_requires =
  appdirs
  koji
  typing_extensions ; python_version < '3.10'

That isn't special syntax for the cfg format itself there, those are passed along verbatim for other tools to interpret.
