Injector rewind: Injectors can now use the method rewind() in order to move the input index backwards, so that they can reprocess tokens (other injectors are not affected by a rewind). This functionality was necessary to implement nested node removals in %AutoFormat.RemoveEmpty. End to start ref: To facilitate rewinding, HTMLPurifier_Token_End now maintains a reference called $start to the starting token for their node. %AutoFormat.RemoveEmpty removes empty nodes. Lots of people have requested it, so here is a partially effective implementation. Because it is implemented as an Injector, it's not possible for it to handle newly introduced empty nodes by later validators, specifically auto-closing and child validation. The Injector is only meant to be used on HTML-ish languages. Signed-off-by: Edward Z. Yang <edwardzyang@thewritingpot.com>
