Should fix a fr warning from https://lukwebsforge.github.io/tldri18n/.

Seems like pages.fr/common/cp.md got translated from pages/linux/cp.md instead of pages/common/cp.md. The common version uses -R and the linux version uses -r, but -R is also valid in linux. So I think it would be the best to just delete the linux page and instead of removing --parents from the french translation we should add it to the english version.

Also all cp pages still use the short form for their arguments, even though there are long forms available for all

[bl-ue]

Yeah, a lot of the pages for essential commands still use short options 🤷🏻 they ought to be fixed.

OK for the history but I am not sure it's a good thing to document common options that are not (common). 💭

--parents is comon, it just isn't listed in common/cp.md. So, the command is the same on all platforms.

Well, not on macOS, visibly:

cp: illegal option -- -

       cp [-R [-H | -L | -P]] [-fi | -n] [-apvXc] source_file ... target_directory

Oh, sorry then. In this case the change seems fine. Thanks.

You're right. I think it should be done in another pull request (I will maybe do it 😇).
