* Fix multienv command
Correctly handles environment variable values that themselves contain "=" (e.g. AWS session tokens)
Ensures that trailing "\n" does not get published as part of the last environment variables value.
* Correct check for empty result in multienv
Check the length of the result string instead of splitting it first and checking the length of envvars (since split always returns an array of length 1)
