Oh, now I understand, I didn't realize the tree was being stored in
human-readable form as a string, but thought it was being parsed into
a binary form.  That's why I began having doubts that I might've triggered
unecessary work on Jan's part regarding lztext.  Yes, since it's
stored as a text string lztext should help a LOT.
