exit inside fish_prompt function doesn't exit immediately

[rnhmjoj]

Issue description

When the exit command is executed inside fish_prompt, the shell doesn't exit unless some a command is typed and executed (pressing enter alone doesn't work).

Steps to reproduce:

set config.sh to

function fish_prompt
  echo '$ '
  exit
end

run fish and notice it doesn't exit.

I'm doing so because I have a "launcher" mode where the shell exits after executing a single command.

That's what fish -c 'command' is for.

The current behaviour is interestingly broken, though, and I think should be fixed.

I mean I'm using the shell as a launcher, so I need interactivity. It's like a shell session but it closes before drawing the prompt a second time.

That's

fish -c 'read -P "PROMPT " --shell -l command; eval $command'

Thank you, I didn't know about read --shell. This solves my problem, the bug is still relevant, though.

Fixed in ba2e7db. Neat find.
