alias functions with escaped (\) char are not displayed as alias

[hashier]

You can see in the screenshot, if you create an alias without \ the function shows up in alias but not if created with an escaped space.

This is because this regexp is not matching anymore:

fish-shell/share/functions/alias.fish

Line 20 in d3e720a

set -l output (functions $func | string match -r -- "^function .* --description 'alias (.*)'")
