That depends if zsh's `equals` option is set or not. If it's set (as it is by default) you'll get that behavior. If it's unset (`setopt no_equals`) that should behave as in bash. But, it fixing the code to work regardless of shell options is definitely a good thing.
This commit changes `==` to `=` for both Bash and Zsh.
An alternate fix would be to switch to using double square brackets instead of single square brackets for the test. Since contents of double brackets have their own parsing rules the `equals` option doesn't apply there, and so `==` is available for checking equality same as in bash. IMHO, this provides saner behavior in general; although it's definitely not POSIX compliant.
