Comment:

 This is a long-standing problem, see #459 :-)

 The "possibly incorrect indentation" message arises because the token the
 parser is looking at is one that was generated by layout.  I honestly
 don't know whether there's anything we can easily do to improve matters in
 the context of the current parser, but I suspect not.

 Anyway, I propose to look at it next time I'm in the area.
