Hyphen is already allowed.  Colon can be a bit tricky, because of
things like

    [[SomeGroup.http:subtext]]

which might look like a url to some if "SomeGroup." isn't present.  
And of course, there are the potential conflicts with InterMap links.

Still, I can't think of anything currently in PmWiki that will 
specifically disallow the colon in pagenames, if one is willing to 
accept that there may be conflicts with url protocol prefixes and 
InterMap prefixes.  

There is the (small, shrinking) possibility that we would use 
{PageName:var} instead of {PageName$:var} for text fields, and this
would of course pose a conflict.

Anyway, to answer the question -- we'd need to adjust $NamePattern to
allow colons, and get MakePageName() to not strip colons in the
pagename.  So, in config.php:

    $NamePattern = '[[:upper:]\\d][\\w:]*(?:-[\\w:]+)*';
    $PageNameChars = '-:[:alnum:]';

There are still probably some other things that would have to
change to make this work, but the above is a pretty good start.

I think that MediaWiki's use of the colon tends to be more like
PmWiki's wikigroups than a straightforward part of the pagename.
But I could be wrong about that.  :-)

Aye.
