Re: [Fab-user] I can't respond to prompts using Fabric "shell" or "run" verbs

[Niklas Lindström]

Hm. Of course, I can just *use* getpass here, although I loose some of
the `prompt` features. Remaining then is whether some secret expansion
is still desirable (the solution of which may or may not make the
usecase of `secret_prompt` interesting again)..
