What were you trying to do (and why)?

Run a command to determine if and local versions of a formula/cask exist. For example:

%brew ls --versions doesnotexist; echo $?
0

What happened (include all command output)?

The process exited normally

What did you expect to happen?

In versions 4.3.3 and earlier, this command would have an exit code of 1.

Step-by-step reproduction instructions (by running brew commands)

In a terminal, run:
brew list --versions doesnotexist; echo $?
