Typo in new wptexturize() pattern

[danielbachhuber]

In r19795, the following:

$dynamic[ '/\'([\s.]|\Z)/' ] = $closing_single_quote . '$2'; // closing single quote

should instead be:

$dynamic[ '/\'([\s.]|\Z)/' ] = $closing_single_quote . '$1'; // closing single quote

The former removes the space from after the new pretty single quote

In [19907]:

Use correct reference in regex. props danielbachhuber, fixes #20018.

Nice catch, thanks.

Everything passed the unit tests after r19795, but the ones that maintained whitespace were not tested for that. I added ​http://unit-tests.trac.wordpress.org/changeset/526, which fails before [19907] and passes now.
