Problem with fish and brew

[danielintempesta]

Describe the bug

Hi. After installing brew on Aurora (latest) and using fish as shell, I get the following message when running fish:

[: the last argument must be ']'

/usr/share/fish/vendor_conf.d/brew.fish (line 7): 
            if  [ ! -L (brew --prefix)/share/fish/vendor_completions.d/brew]
                ^
from sourcing file /usr/share/fish/vendor_conf.d/brew.fish
	called on line 248 of file /usr/share/fish/config.fish
from sourcing file /usr/share/fish/config.fish
	called during startup

(Type 'help [' for related documentation)

What did you expect to happen?

Line 7 of /usr/share/fish/vendor_conf.d/brew.fish must be

if [ ! -L (brew --prefix)/share/fish/vendor_completions.d/brew ]

Thanks
