Fix for fish gcp after the recent change.

Working well on my machine now! @carlfriedrich would you review and make sure this seems reasonable?

@wfxr would you try gcp with your config just for some QA and make sure it's running well :)

Looks good to me! Sorry, I thought I had tested this in fish, but it turned out that my test environment wasn't clean.

No apologies necessary! happens to me all the time 😄

Thanks for the look over, going to merge

@cjappl Sorry for the late reply. It works as expected in zsh.
