[PATCH] zsh completion: 5.0.3 compat, use emulate

The bash completion pulled into zsh was being pulled in _as_ zsh, but used patterns which relied on falling through as unhandled. In zsh 5.0.3 this no longer works, resulting in:

    __git_complete_remote_or_refspec:33: bad pattern: +*

Fix by telling zsh to emulate sh while sourcing the bash config file, which stickily preserves compatibility options in the function context. This usage of "emulate" came in with zsh 4.3.10, released 2009-06-01.
