Here's an alternative to a case by case disabling of zsh completion, or
renaming commands.

    1. To plain old fall back on filename completion:

	    zstyle ':completion:*' completer _expand _complete _files \
		_correct _approximate

       The important thing above is the "_files" entry. This means if
       expansion or completion fails, it will try filename completion.
       (If that fails too, it will try correction or approximation.)

    2. Define a widgit that just completes files, and bind it to
       something (e.g. <C-X>f, in the example below).

	    zle -C complete-file menu-expand-or-complete _generic
	    zstyle ':completion:complete-file:*' completer _files
	    bindkey -M viins '^Xf'      complete-file
    
       (Change -M viins to -M emacs if you don't use VI keys)

       This allows you to complete files anywhere, on any command, at
       any time, by pressing <C-X>f (i.e. Control X, followed by f).
