This was overly smart and tried to not show you e.g. global variables
unless you were setting without scope or explicitly global.
That is annoying when you do
`set -g fish_col<TAB>`
and don't get colors because they're universal, but you could
overwrite them.
We *could* elide e.g. local variables if we're setting a global, but I
can see someone wanting to set a universal variable on basis of a
global ("save this"), so I would rather not try to find the very
specific cases where this works.
