Special characters in `expect` for matching Bash prompts

[rudolfbyker]

Is your feature request related to a problem? Please describe.

I'm trying to match a bash prompt like user@host:~$ but special characters like : and ~ and $ don't seem to work in the expect field. It never matches.

Describe the solution you'd like

I would expect this regex to work: \w+@\w+:~\$.

Describe alternatives you've considered

This is what I'm using instead, but it's not ideal: \w+@\w+.{3}
