enable make style-all doing fish scripts

I had disabled having `make style-all` restyling fish scripts because a
majority of them did not conform to the style enforced by `fish_indent`.
I recently restyled most of the fish scripts with the exception of the
completion scripts. So this re-enables restyling all scripts with the
exception of completion scripts.
