Prior to this change we would recover the names for known
externals by looking up the span in the engine state. This would fail
when using an alias for two reasons:
1. In cases where we don't have a subcommand, like this:
```
>>> extern bat [filename: string]
>>> alias b = bat
>>> bat some_file
'b' is not recognized as an internal or external command,
operable program or batch file.
```
The problem is that after alias expansion, we replace the span of the
expanded name with the original alias (this is done to alleviate
non-related issues). The span contents we look up therefore contain `b`,
the alias, instead of the expanded command name.
2. In cases where there's a subcommand:
```
>>> alias g = git
>>> g push
thread 'main' panicked at 'internal error: span missing in file contents cache', crates\nu-protocol\src\engine\engine_state.rs:474:9
note: run with `RUST_BACKTRACE=1` environment variable to display a
backtrace
```
In this case, the span in call starts where the expansion for the `g`
alias is defined and end after `push` on the last command entered. This
is not a proper span and causes a panic when we try to look it up. Note
that this is the case for all expanded aliases that involve a
subcommand, but we never actually try to retrieve the contents for that
span in other cases.
Anyway, the new way of looking up the name is arguably cleaner
regardless of the issues mentioned above. But it's nice that it fixes
them too.

This commit renders ANSI chars in order to provide shell integrations
such Kitty's opening feature that captures the output of the last
command in a pager such as less.
Fixes#5138
- With a change to reedline hints can now be hidden. This is useful when
no ANSI coloring is available as hints become indistinguishable from the
actual buffer
- remove commented out code
- order the logging calls according to the implementation
* Fix failing unit tests on Windows (#5142)
Fix let_env_expressions failing on Windows:
The env expression uses PATH, but on windows Path is used.
Fix correctly_escape_external_arguments, execute_binary_in_string
failing on Windows:
Using cococo now to make sure testresults are platform independent
* Update macros.rs

I don't personally agree with this; I'd prefer less magic,
and not expanding _anything_ except `~` as an initial path element

To remove a default keybinding for a particular edit mode, set the `event: null`:
e.g. to disable screen clearing with Ctrl-L
```
let $config = {keybindings: [{
modifier: control
keycode: char_l
mode: [emacs, vi_normal, vi_insert]
event: null
} ]}
```
