I'm not sure this regexp will give correct results.

Actually I don't think you can come up with a regexp for this problem that
works correctly (in the sense of the resulting buffer text) and that also
allows my code to avoid changing the buffer when it's not needed.
It's a limitation of my code.  It can probably be lifted with
a (skip-chars-forward "\t").
