Before 71fd19d7ac this function went
through a `:!` command on all platforms, so it needed special escaping for `#` and
others. After that commit it doesn't go through that path on unix
platforms. Then with 48581f2ba9 this
escaping was re-added on unix and it's needs since it goes through
`sh -c`, but it should not have the extra escaping specific to `:!`.
Specifically my original broken command is:
```
PATH=/usr/bin:/bin VIMRUNTIME=~/dev/vim/runtime ./src/vim -u NONE -c 'call dist#vim9#Open("7bce9f5c69/vimrc (L19)")'
```
Where the `#L19` ends up being opened as `%5C#L19`. But I verified this
case still works as well:
```
PATH=/usr/bin:/bin VIMRUNTIME=~/dev/vim/runtime ./src/vim -u NONE -c 'call dist#vim9#Open("foo bar.txt")'
```
Which is what would otherwise break if we weren't doing any shell
escaping on unix.
