issue shell block quote is not always directly about formatting shell scripts

[ccoVeille]

shfmt is made for formatting script, definitely.

```shell
#!/bin/env bash

    date

But shell block quote in markdown is not ONLY about that

Yes, this would be valid

````markdown
```shell
  cp   foo    bar
  touch   foo

But the alternative syntax used in many markdown linters is this one

$ command result

So this

````markdown
```shell
$ date
Tue Apr  2 23:54:37 CEST 2024

Please note this one is sometimes refered as `console`

````markdown
```console
$ date
Tue Apr  2 23:54:37 CEST 2024

````markdown
```console
foo@bar:~$ whoami
foo

So your script will try to format things that are not always script.

I'm not sure about the consequences of the things I'm raising, but at least now you know they exist

Hmm, as far as I can tell shfmt doesn't have any issues formatting lines starting with $ (But it can't parse mdsf format <PATH_TO_FILE> which is rather ironic).

     $  cp   foo    bar
        $     touch    foo
$ date
Tue Apr  2 23:54:37 CEST 2024

Becomes

$ cp foo bar
$ touch foo
$ date
Tue Apr 2 23:54:37 CEST 2024

From a ux perspective I would personally expect any block tagged with shell / sh to be formatted using the shell formatter, whether it has a shebang or not. But I can definitely see your point.

I am honestly not sure what makes most sense 😅

Yes, exactly. My idea was for your to have this in your mind. Maybe add a test or twos.

So you can see how things evolve.

Because developing is east, maintaining is hard. So having unit tests is always better.
