(As suggested in 84e7fbd466 (Make default .theme file consistent with uvars,
2022-02-03))
Historical behavior in default fish is that
1. fish_color_keyword and fish_color_option are unset, meaning they
default to their fallbacks, fish_color_command and fish_color_param.
2. colors not mentioned in the default them, such as
fish_pager_color_secondary_background, are unset
"fish_config theme save fish\ default"
- sets group 1 to a non-empty value (deactivating the fallbacks)
- sets group 2 to an empty value (which has no function change except it
changes completions for builtin set)
Both are probably fine. I guess the historical behavior is a bit nicer.
But the new behavior is simpler. We can definitely optimize it later,
for example by never redundantly setting universal color variables to an
empty value.
