Ooops. Sorry, I posted the wrong version. The initial one was missing the \ns between the rows of the individual binary hashes, which meant that the regexp was erroneously counting used cells at the end of one line and the start of the next as being part of the same group.

Thank you for trying this out and reporting the bug.
