Not exactly. When a page is saved, the markup it contains is evaluated, that  
is, the wikitext is converted to HTML, in order to keep track of the link  
targets.

With a few exceptions: redirects, inclues, conditionals, pagelists,  
searchresults, and wikitrails are not evaluated. The "(:include ...:)"  
markups on the page are replaced with " " (space) before the text is  
evaluated, same for the other markups.

That means that all other markup, including (:pmform:), will be evaluated  
and if it contains a WikiLink, it will be indexed.

You can disable the evaluation of the (:pmform:) markup by adding this to  
config.php:

  $SaveAttrPatterns['/\\(:pmform(\\s+.*?)?:\\)/i'] = ' ';

I wonder if this should be added to the pmform.php file.
