That will usually work, except for corner-cases where redisplay happens
in the middle of a command, or when the selected window is modified
between commands (e.g. from a process sentinel).
You can make it reliable with the use of the new
`pre-redisplay-function' hook (instead of post-command-hook), which
I just added yesterday.
Of course, making it reliable doesn't mean it's not an omission.
I tend to agree that it would be good to provide access to that info
more directly.
