Changeset 3495 for pkpgcounter

Message:

Now correctly handles the <ESC>$b???W sequences.
IMPORTANT : a post-parsing adjustment was done for ImageRunner?
documents, which incremented the page count. This adjustment **might**
have been needed because of this bug. A new adjustment is now done for
ImageRunner? files, which decrements the page count instead. Seems to
work on the set of test files. Fixes #40.
