I agree with the strangeness of the name, but the problem is that we have inconsistent behaviour. Currently Fossil:

  *  Allows creating a new page with dot in the beginning here: Note that there are rules for names listed on this page; and ".Pagename" is okay by these rules.
  *  But when linking to such pages via <nowiki>[.Pagename]</nowiki> syntax, links don't work correctly (should point to but point to

We should either disallow creating wiki pages with "." in the beginning and update the rules, or fix the link formatting.
