Browse Source 
... in tjLoadImage()/tjSaveImage().  These error codes require an add-on
message table, and if it isn't initialized, then format_message()
produces "Bogus message code XXXX" instead.

3. Fixed an issue whereby the `tjLoadImage()` and `tjSaveImage()` functions
would produce a "Bogus message code" error message if the underlying bitmap and
PPM readers/writers threw an error that was specific to the readers/writers
(as opposed to a general libjpeg API error.)
