Motivation:
`--color base16` can be a better default than `dark` or `light`, since it uses
the colors defined by the current theme. This usually blends in more
naturally and works well in both light and dark modes.
However, some elements were previously hard-coded with white or black
foreground colors, which can cause rendering issues in certain terminal
themes.

Example:
# Implement popup that disappears after 1 second
# * Use footer as the popup
# * Use `bell` to ring the terminal bell
# * Use `bg-transform-footer` to clear the footer after 1 second
# * Use `bg-cancel` to ignore currently running background transform actions
fzf --multi --list-border \
--bind 'enter:execute-silent(echo -n {+} | pbcopy)+bell' \
--bind 'enter:+transform-footer(echo Copied {} to clipboard)' \
--bind 'enter:+bg-cancel+bg-transform-footer(sleep 1)'
Test cases:
1. 'jump' should show alternating background colors even when 'alt-bg' is
not defined as before.
go run main.go --bind load:jump
Two differences:
* The alternating lines will not be in bold (was a bug)
* The marker column will not be rendered with alternating background color
2. Use alternating background color when 'alt-bg' is set
go run main.go --color bg:238,alt-bg:237
go run main.go --color bg:238,alt-bg:237 --highlight-line
3. 'selected-bg' should take precedence
go run main.go --color bg:238,alt-bg:237,selected-bg:232 \
--highlight-line --multi --bind 'load:select+up+select+up'
4. Should work with text with ANSI colors
declare -f | perl -0777 -pe 's/^}\n/}\0/gm' |
bat --plain --language bash --color always |
go run main.go --read0 --ansi --reverse --multi \
--color bg:237,alt-bg:238,current-bg:236 --highlight-line
