Hmm, actually I have no idea, so I just checked. Seems I was slightly
wrong in my description; the guides seem to be at fixed column
positions (configurable, but not dynamic). The differentiation between
tab and space is only for its signalling highlight - if you mismatch
indentation in any way, the wrong one is highlighted with a very
visible marker. And that highlight correctly accepts your above
example, though it's a little finicky to type (putting a space, then a
tab, on an otherwise-blank line deletes the space, but one can be
explicitly inserted after the tab's already there). The upshot is that
you get instant feedback if you ever get tabs/spaces wrong, and you
get nice guides if you always indent consistently, and in between is
shooting yourself in the foot anyway.
