This change provides the following improvements:
- Changes the view of the command history list, so that the script no longer depends on perl for performance.
- Enables syntax color highlighting on fish v4.3.3 and newer.
- Provides a preview window with the selected commands, and expanded view of the highlighted command if available.
- Improves the delete functionality, by successfully handling very large numbers of selected commands.
- Inserts commands in their formatted form with `<Alt-Enter>`.

* fish: Change history list view
The view of the command history is changed, so that no manipulation is
performed on the output of history command: The history item count
number is replaced by the Unix time of the command, multi-line display
is disabled and line wrapping is enabled by default. On fish v4.3.3
and newer, the use of ANSI color codes for syntax highlighting is now
possible, while the script no longer depends on perl for performance.
Fixes#4661
* fish: Reformat selected history commands with ALT-ENTER
* Add $FZF_WRAP environment variable
The variable is set when line wrapping is enabled. It has the value
`word` if word wrapping mode is set, otherwise it has the value `char`.
* fish: Add command history preview
The preview shows the highlighted command and any selected commands,
after first being formatted and colorized by fish_indent. The timestamp
of the highlighted command in the preview is converted to strftime
format "%F %a %T" if the date command is available.
The preview is hidden on start, and is displayed if more than 100
columns are available and one of the following conditions are met:
- The highlighted item doesn't completely fit in list view (line
wrapping is enabled for the preview and is now disabled for the list).
- The highlighted item contains newlines (multi-line commands or
strings).
- The highlighted item contains chained commands in a single line, that
can be broken down by the formatter for cleaner view.
- One or more commands are marked as selected.
* fish: Handle deletion of large number of selected history entries
* fish: Change wrapping options for the preview-window
Support double, curly, dotted, and dashed underline styles via --color
(e.g. underline-curly) and ANSI passthrough (SGR 4:N, 58, 59) with --ansi.

Thanks to @shtse8 for the test cases.
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
