Warnings are the wrong answer to this problem.  In fact,
they're rarely the right answer to any problem. Tabs in
sourcecode can have bad effects, and Haskell is a language
that attempts to reject bad effects as far as possible. Nor
can I see any argument in favour of allowing tabs (if HT is
allowed, why not VT?).
