Can't paste multi-line statements into CLI

[nukep]

This is a rather frustrating bug/limitation for those of us who like to copy and paste multi-lined text into the CLI. If a multi-line string is pasted, only the first line will be inputted.

rust-linenoise is used to drive the CLI input. Enabling multi-line mode with linenoise::set_multiline(1); doesn't seem to have any effect on my machine (64-bit Linux, using gnome-terminal).
