Test failures on MacOS with latest pull from git

[Bart Schaefer <schaefer@brasslantern.com>]

This is actually the first time I've tried building the pcre module on
MacOS, so the first error is probably related to my system setup.

./V07pcre.ztst: starting.
Testing PCRE multibyte with locale en_US.UTF-8
Test ./V07pcre.ztst failed: bad status 2, expected 0 from:
  [[ 'foobar' =~ .([^[:ascii:]]). ]]
  print $MATCH
  print $match[1]
Error output:
(eval):1: module `zsh/pcre' has no such feature: `C:pcre-match'
(eval):1: -pcre-match not available for regex
Was testing: Basic non-ASCII regexp matching
./V07pcre.ztst: test failed.

This one looks to be from Oliver's recent vi-mode changes:

./X02zlevi.ztst: starting.
