Improvements and fixes to zsh completion
* Use correct return status so that approximate completion isn't broken * Follow zsh conventions on description forms * Some options can be used multiple times, e.g. -H, -r, --file-name * Set completion context correctly for the cache subcommand * Better completion for --map-syntax argument * Add --nonprintable-notation option * Correct some of the mutual exclusion lists for options
