00281: Subdirectories in wiki.d when url more than two levels deep
Description: From a cursory examination, wiki links that are of the form Main/Foo get stored as Main.Foo in wiki.d, and Main/Bar/foo saved as wiki.d/Bar.Foo
If subdirectories could be made then .htaccess files could be used to control access by user, IP address, etc. so that third level or greater links would be located as follows
[[Main/Bar]] located in wiki.d/Main.Bar
a link [[foo]] in page Bar makes wiki.d/Bar/Bar.foo
[[Main/Bar/foo]] in Main also in wiki.d/Bar/Bar.foo
a link baz in Bar back to a page in Main would be [[Main/baz]] or [[../baz]]
Also modify hiearchy display at top of page to reflect nesting level of current page.
So far we've declined to support multi-level pages; see PmWiki.HierarchicalGroups for an explanation of why. --Pm
