Yup, this will require a custom LinkPage function. In this case,
just use $LinkFunctions['<:page>'] = 'MyLinkFunction';

Oh, finding and removing them is fairly simple -- just go ahead and
process the text (via MarkupToHTML) and then strip out the HTML tags.

Well, "not currently allowed" should read "not currently processed" in
link text. The link text allows the other markups, they just don't get
handled as normal.

Very messy--I probably don't want to go there as it ruins the
symmetry of what is already working. I'd prefer to move the
"safe" inline markups to be processed before link processing, or
rename the "inline" markup section to mean something indicative of
the fact that it occurs after link and block processing.

The problem is that the LinkText isn't available at the time
"inline" is currently processed--the LinkText is held in Keep()
values at this point. It doesn't get restored until just before
WikiStyles are processed.
Which of the existing markups should we allow to occur in link text,
and what conflicts might they have with links? Would it be sufficient
to simply move the whole "inline" section to before "link" processing?
In a quick glance at PmWiki's default markup, I don't see a major
problem with this.
