Description: in local/config.php put the following:
$WikiWordCount["TestWikiSpacingWord"] = 0;
Then in a page write TestWikiSpacingWord - The word is correctly not rendered as a link, but it does still come out spaced.
Technically this wasn't a bug, but starting in pmwiki-2.2.0-beta14 one can now set:
$WikiWordCount["WikiWord"] = -1;
and this will cause WikiWord to be neither linked nor spaced.
