Whoops.  Looks like there's a realistic situation in which this pops up,
and looks bad: Bug#4281.  I committed a fix for that (revno 107654),
before remembering about the discussion in this thread and the decision
to leave it alone.

I guess I could revert the fix.  But first, is there a work-around for
Bug#4281?  The line prefix applied by org-indent-set-line-properties
does have an explicit `face' property, but that didn't seem to stop the
global-hl-line-mode highlighting from leaking into the prefix.
