This would appear to be an un-remarked change to the Report since
version 1.2.  That version states that "program lines have the
leading '>' replaced by a leading space, to preserve tab alignments".
Version 1.3 removed this specification, and the changed specification
only appeared in Haskell'98.

I would like to submit it as a bug in the Report - the older
specification, as implemented by Hugs and nhc98 makes more sense in
conjunction with the layout rule.
