@defun buffer-chars-modified-tick &optional buffer
This function returns @var{buffer}'s character-change modification-count.
Changes to text properties leave this counter unchanged; however, each
time text is inserted or removed from the buffer, the counter is reset
to the value that would be returned @code{buffer-modified-tick}.
By comparing the values returned by two @code{buffer-chars-modified-tick}
calls, you can tell whether a character change occurred in that buffer
in between the calls. If @var{buffer} is @code{nil} (or omitted), the
current buffer is used.
