I hate doing this but I am tired of touching a fish script as part of
some change and having `make style` radically change it. Which makes
editing fish scripts more painful than it needs to be. It is time to do
a wholesale reformatting of these scripts to conform to the documented
style as implemented by the `fish_indent` program.
This was causing issues launching fish_config on OS X if fish.app is
renamed to contain a space (noted, but likely not the actual problem,
in issue #3140)
