Yeah, I forgotabout speakup's indent notification; you have to do that
on every line you scroll across though. 

Anyway, I think emacs does that mixed space and tabs thing to line up
indented if statements and other blocks plus sometimes with that
indentation, the number of columns to indent don't equal a multiple of
the number of spaces in a tab stop.  Like if the typical tab stop is
eight spaces and you want to indent 12, then you would end up with a
tab plus 4 more spaces.  Of course, this can be remedied by setting
the tab stop size to 4 chars in this case.  I think emacs can be
configured to do just that.  Guess I better read up on emacs' indent
stuff and see how flexible it really is.
