That was really just a typo in the mail. On the command line, the
space was quotred.

That youldn't help because a taxon can be one to four words, at
least, possibly more.

Isn't there a way to switch it off for a specific command?
Reading the examples I'd have guessed that
zstyle ':completion:*' completer _complete _match _approximate
zstyle ':completion:*:*:foo' completer _complete _match
Would turn off the _approximate completer for the foo command, but

Well, keeping this in mind; the approximation stuff may not be
that important anyway.
