+Things which have been suggested but will not be done
+ Recursive file processing
+ A -r flag might be nice, but this is best handled by an exterior shell
+ script.
+
+ Make perltidy support the syntax of some module XXX.
+ This generally won't be done unless the module is part of the core perl
+ distribution. But in some cases it might be possible to use the prefilter
+ and postfilter capabilities of the Tidy.pm module to help.
