Add parallel[match] marker

[connorjward]

Basically

$ mpiexec -n 3 pytest tests -m parallel[match]  # match parallel[3] tests

$ mpiexec -n 2 pytest tests -m parallel[match]  # match parallel[2] tests

Happy to be bikeshedded. Unfortunately -m parallel[?] and -m parallel[#] break bash.

Thanks for doing this, I'd completely forgotten about this!

The implementation looks fine.
Bike shedding incoming: what about parallel[.]?

Edit: . might be annoying if we want to query commands with grep/sed later.

FWIW I prefer parallel[match] to parallel[same], but really either one is fine

Happy to be bikeshedded. Unfortunately -m parallel[?], -m parallel[#] and -m parallel[?] all break bash.

-m 'parallel[?]'

(i.e. with single quotes).

But that's probably not very discoverable

I find it annoying to have to put quotes in. I don't particularly like same. Just need more suggestions. Annoyingly the tests that run fine locally are failing with

Can you add this to the main README too please?

I may have a workaround...
