ridiculousfish 6a6ffe68cb Make __fish_describe_command stop barfing on /
Prior to this fix, __fish_describe_command would error if the
input contained any special characters, because it would be interpolated
into a regex. Hack in a guard to do nothing if the input contains
anything other than [a-zA-Z0-9_ ]
