expected a borrowed string for key with backslash in key binding

[ds-cbo]

Breaking version: helix 22.12 (0f2ae35a)
This worked fine in 22.08

Config:

[keys.normal]
"3" = [
  ":pipe sed -E 's/\\s+$//g'"
]

Command:
./target/debug/hx --config /tmp/config.toml -vvv --log /tmp/helix.log

Error:

Bad config: invalid type: string ":pipe sed -E 's/\\s+$//g'", expected a borrowed string for key `keys.normal.3` at line 3 column 3

This seems to be caused by the double backslash in the command. Replacing it with :pipe sed -E 's/ +$//g' fixes the issue for now.

Log:

Nothing interesting

This is fixed by e83ce72 but this particular keymap doesn't actually work regardless because helix performs some additional escapes (even when typing the same keymap inside helix). I found :pipe \\'\\s+/,/g\\' to work when typed into helix but not as a keymap (rI tried a bunch of extra escapes but didn't manage it, the command doesn't even get dispatched). Not too sure how to fix that tough and I think that's (partially) intentional and not what this issue is about. #5144 is more or less the same fix as e83ce72 tough (there is nothing additional there which would fix the behavior I described)
