The -k expression works with double quotes but not single quotes

See original GitHub issue

When using single quotes and trying a conjunction of expressions: -k 'vet_a and vet_a' I get the error message: ERROR: file or directory not found: and

I finally tried double quotes and it worked.

Note: the docs and -h help text using single quotes in the -k examples so at least update those as a quick workaround…

On unix systems, ' is the better option because it avoids shell interpolation.

On windows systems, looks like the correct quoting is double quotes (at least according to a random Stack Overflow answer…).

(edit: NOTE: see comments below) So it would be nice I suppose for pytest to use double quotes on windows and single quotes everywhere else in its help text for -k (and any other options which use quotes in their examples, if any).

PR welcome!

-h output is set here: https://github.com/pytest-dev/pytest/blob/176d2d7b4e21b19fb08afdb3f9db61495eff5647/src/_pytest/mark/__init__.py#L86

Also, doesn’t -m option have the same behavior about quotes as -k?
