Bug report
Bug description:
activate.csh uses "$prompt" in quotes like that, which fails when the user prompt contains a newline (error: unbalanced quotes).
Using $prompt:q or "$prompt:q" solves this with no harm, at least in tcsh (not sure about vanilla csh), at least for activate. (Deactivate may have similar issue.)
