I'd be in favor of changing `kill-whole-line` to do the kill in a single
step rather than killing the "before" and "after" separately.
I understand why it doesn't do that, but I'm not sure it's worth the
trouble (or we should change the `kill-region` thingy to be more
robust, e.g. record the position of the last kill so that it doesn't
need to rely on (< end beg) to guess whether to append or prepend and
it can automatically notice when the new kill is *around* the previous
one).
But in addition to that, I suspect that Org should probably not modify
visibility directly from the modification hooks. Instead, its
modification hook function should just stash the info somewhere and then
update the visibility later on, such as in a `post-command-hook`, timer,
`pre-redisplay-functions`, younameit.
As a rule of thumb, I think modification hooks should be treated a bit
like POSIX signal handlers: just record the event somewhere but don't do
any substantial work in there.
