Run fish_indent on all our fish scripts It's now good enough to do so. We don't allow grid-alignment: ```fish complete -c foo -s b -l barnanana -a '(something)' complete -c foo -s z -a '(something)' ``` becomes ```fish complete -c foo -s b -l barnanana -a '(something)' complete -c foo -s z -a '(something)' ``` It's just more trouble than it is worth. The one part I'd change: We align and/or'd parts of an if-condition with the in-block code: ```fish if true and false dosomething end ``` becomes ```fish if true and false dosomething end ``` but it's not used terribly much and if we ever fix it we can just reindent.

Correct handling of explicitly separated output when all elements are empty Previously when propagating explicitly separated output, we would early-out if the buffer was empty, where empty meant contains no characters. However it may contain one or more empty strings, in which case we should propagate those strings. Remove this footgun "empty" function and handle this properly. Fixes #5987
