One minor annoyance is that the suggested .pertidyrc file is not included in the source packet from O'Reilly.

Also, the -wbb option in the .pertidyrc looks a bit... odd. >= is there twice, as is <, unless I'm reading it wrong.

Ah, looking at the perltidy perldocs, looks like this is just an artifact of copying the perldoc's "break after" list into the "break before" list. So it's an inherited bug, if it's a bug...
