For me it's not nonsensical at all:
1. emacs -Q
2. M-x html-mode
3. M-x column-number-mode
4. eval the above defvar and defun
5. insert <html></html>
6. put the cursor on the leftmost `>'
7. C-c C-i
=> I hear two beeps, then "<html></html>" disappears and I see "... 2"
in the echo area. No further beeps or CPU consumption.
When I repeat C-c C-i the tags reappear, when I repeat C-c C-i again,
they again vanish after two beeps and the message is now "... 4". And
so on, each time incrementing by two.
