Subject: [PATCH] opam: fix enableFishIntegration (#3597)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fish shell doesn't require arguments to `eval` to be double quoted
like in a bash shell. At the moment doing so gives us the following
error:

~/.config/fish/config.fish (line 12): $(...) is not supported. In fish, please use '(/nix/store/8asq…)'.
eval "$(/nix/store/8asqgnhs89wzyjvs8p1n5hvxn7lkn9wa-opam-2.1.3/bin/opam env --shell=fish)"
      ^
from sourcing file ~/.config/fish/config.fish
	called during startup
source: Error while reading file “/home/user/.config/fish/config.fish”

This commit fixes the above error.
