That's not a likely pagename on this particular site :)

I knew hyphen is allowed.  The trick is getting the colon in there.

Can the intermap delimiter be changed? LOL

It's not working.   I personally prefer perl (PCRE) over posix (PREG)  
regexes....

In posix regex, : does not seem to need to be escaped, but your  
regexes didn't work.

I put [[Group/OfMiceAndMen:SteinbeckJohn:HerHairHung]] on a page.   
Click it and it brings me to a "create page screen" where the  
pagename is
Group/OfMiceAndMenSteinbeckJohnHerHairHung

I know the regexes you hinted at are (not) working because I managed  
to break them while tweaking to see if I could fix them.
Original pmwiki.php line
//pmwiki.php:43:$NamePattern = '[[:upper:]\\d][\\w]*(?:-\\w+)*';
$NamePattern = '[[:upper:]\\d][\\w]*(?:-[\\w:]+)*';
$PageNameChars = '-:[:alnum:]';

I tried
$NamePattern = '[[:upper:]\\d][\\w]*(?:-[\\w]+[:]+)*';
and that failed also.
$PageNameChars=':-[:alnum:]';
blew up with fireworks

and $PageNameChars='-[:alnum:]:';
had no discernible effect

$MakePageNamePatterns = array(
     "/'/" => '',			   # strip single-quotes
     "/[^-:[:alnum:]]+/" => ' ',         # convert everything else to  
space
     "/((^|[^-:\\w])\\w)/e" => "strtoupper('$1')",
     "/ /" => '');
in my config.php didn't help either.  Note I changed the 3rd pattern  
to include the colon (the 2nd I put the $PageNameChars instead of the  
variable, just in case).

So colons are still being turned into spaces/being stripped..

Yes, but before then I hadn't realized that : was a legal URL  
character aside from http:
