The command_not_found_handler in zsh behaves different than its bash equivalent (command_not_found_handle)
Issue
Both zsh and bash have a feature where a handler can be defined, to intercept the situation when a command is launched, but not yet available on a system.
The mechanism implemented in bash, allows to differentiate between an issue with the handler (for example a user did choose not to install the program), or a non-zero return code from the program, which was just now installed by the handler. This is not possible with `zsh', currently, it returns either 0 on success or 127 on any error, be it in the handler or in the installed program.
