quitcd not working in fish if path contains backslash

[Ordoviz]

If you press ^G to exit nnn or have configured quitcd, nnn writes a cd command in POSIX-shell syntax into ~/.config/nnn/.lastd. While fish syntax is similar to POSIX, they differ on their handling of backslashes in single-quoted strings. In particular, if nnn writes a path ending in a backslash into .lastd, and you source .lastd in fish you get Unexpected end of string, quotes are not balanced.

To fix this, nnn should write the raw (unescaped) path to ~/.config/nnn/.lastd_raw or stdout so that you don't need to parse the escaped path in fish. This would probably also be helpful for nushell, where you currently need to do some horrible string parsing to extract the path from .lastd.

Hey, it's not terrible! It's just... tricky!

But yep, it'd be better for Nushell as well the raw path.

Oh, I just realized the bug is in fish shell not nushell. Anyways...

or stdout

Stdout can be used by plugins, so no.

The path for last directory is not hardcoded, it depends on $NNN_TMPFILE. Randomly adding new temp file or changing the format of the existing file isn't good. Feel free to send a PR fixing the fish shell script instead.
