Failing to omit files through setup.cfg

[SebastienMorais]

Describe the bug
In my setup.cfg file, I specify that i want to omit my test files when measuring coverage:

[coverage:run]
omit = *tests/*

While this worked a few version ago (at least in 6.5), current version (7.1.0) does not omit the tests files.
This can be fixed with the following setup

[coverage:run]
omit = my_package/tests/*

Although it is possible to make everything work (as specified), I am surprised that my previous configuration no longer works.

To Reproduce
I'm using python 3.8.14 with coverage 6.5 and pytest 7.2.1.
The command used is:
coverage run -m pytest --cov=my_package --cov-fail-under=95 --cov-config=setup.cfg

Expected behavior
I would expect that omit through *tests/* would omit every files contained in my_package/tests/

The interpretation of wildcards changed between 6.x and 7.x. It will work if you use omit = */tests/* I think. In 6.x, * would match a directory separator, but now it does not.

I think we could use a more complete description of the wildcard changes, and how to adjust settings when moving from 6.x to 7.x.

Indeed, it works 👍

@paxnovem added migration notes in commit d6e621a. I hope that will avoid future confusion.
