The idea behind this commit is described on http://oddmuse.org/wiki/Refactoring page.
In short: 'return undef' returns (undef) in list context (a list with one element),
which is wrong.
Replaced the $Id$ tags in $WikiDescription for all the modules and wiki.pl itself with a link to the source and an appropriate wiki page, if possible. This is shown in action=version and should help users figure out what another wiki has installed.
replacement for the Sidebar module, for all Sidebar users
requiring a cleaner integration of that module with other modules
such as "toc.pl" and "footnotes.pl". This new module also improves
Sidebar customizability by permitting users to place the "Crossbar"
at any position in any page.
* modules/forms.pl (FormsRules): Generalized so as to support both
the Sidebar and Crossbar modules.
* modules/toc.pl (RunMyRulesToc): Generalized so as to support both
the Sidebar and Crossbar modules.
* t/crossbar.t: New test suite, testing the Crossbar module.
removing all previous module-specific hacks. However, as it is a
rewrite, it may still have issues. (Fortunately, time is the mother
of invention and bug fixes.)
* modules/toc.pl: Refactored. This is a complete rewrite
removing all previous module-specific hacks. As with "sidebar.pl",
it may still have issues. That said -- I'm relatively proud of it,
and confident that it (should) stand up under rigorous scrutinies,
utilization, and brutalization.
* modules/forms.pl (FormsRule): Slightly revised, so as to comply
with the "sidebar.pl" refactoring.
