However, the implementation here doesn't do what you'd want: it
selects the text, destroying any existing selection. You can work
around it by preserving and then restoring the selection somehow, but
it's not ideal at all. It would make much more sense to have a
function that returned a Range or list of Ranges.
Of course, for the use-case you posted, execCommand() would also have
to work on Ranges instead of just the selection, but that should
probably be feature #1 to add to it anyway . . .
