Repeating options (e.g ENV vars)

[Silex]

Hello,

Do you have an idea about how to support repeating options?

See https://github.com/Silex/docker.el/issues/169 for the background.

Basically we have this command that can have multiple -e flags, and at the moment the only way for the user is to press -e then enter a string like FOO -e BAR -e BAZ (include the multiple flags inside the value of the first flag).

Basically if you solve #1 I think you'll also solve this one.

Closing because there's no elegant solution for this problem at the moment. Might reopen later.
