'pytest -v' shows full path on Windows when pytest.ini is on substituted drive

• minimal example if possible

The subject says it all: pytest on Windows shows full path of the test file in verbose mode when there is a pytest.ini in the current directory and the directory is on a substituted drive:

> pwd
Path
----
F:\cygwin\home\thorsten\python\modules

> pytest -v
platform win32 -- Python 3.8.3, pytest-5.4.3, py-1.8.1, pluggy-0.13.1 -- f:\scoop\apps\python\current\python.exe
cachedir: .pytest_cache
rootdir: C:\data\flash drive\cygwin\home\thorsten\python\modules

> touch pytest.ini

One more observation: creating an empty pytest.ini changes the rootdir log line from rootdir: C:\data\flash drive\cygwin\home\thorsten\python\modules to rootdir: F:\cygwin\home\thorsten\python\modules. This reflects the fact that F: is a substituted drive:

> subst
F:\: => C:\data\flash drive

Changing the subject acccordingly.

What do you think it should display?

[thorstenkampe]

@Zac-HD pytest should display just the file name (as it does on Linux and when the test file is not on a substituted drive). For me it looks like the current path is incorrectly determined. I'm in F:\cygwin\home\thorsten\python\modules - not in C:\data\flash drive\cygwin\home\thorsten\python\modules (the latter is "mounted"/substituted to the former)

Thanks @thorstenkampe!

This will be fixed by #6523. 👍
