You can do this with the ignored-patterns style. On the surface, this
works in the negative sense, e.g.:
zstyle ':completion:*:commands' ignored-patterns messageview messageformat messagesend
But you can use a pattern to turn this around into a positive form, e.g:
zstyle ':completion:*:-command-:*:commands' ignored-patterns 'mess(^ageedit)'
If you still occasionally want to complete the others, you may want to
look into the _ignored completer to complete them as a fallback if you
have entered a longer prefix.
In the second example, I used a more specific context which will only
apply in command position. You can vary that depending on the contexts
in which you want it to apply.
