[pmwiki-users] Attachment links with square brackets in both the filename and link text

[Maxim]

I want to do:

[[Attach:Filename [x].zip | Link Text [x] ]]

I've made a page at
http://www.pmwiki.org/wiki/Test/SquareBracketsInLink with various
iterations of the markup while removing the square brackets. There's
also a version linking to a regular page, although having a square
bracket in the page name is less likely. In both, the parsing seems to
fail for tests 1, 2, 5 and 7. How can I get a link like the one above?
