Warning and glagow-exts instead of glasgow-exts

[nobody]

Take this module (Bla.hs): 

x = [ q | y <- [1..10] | z <- [30..40], let q = z*z]

Loading it into GHCi gives:

[ Bla.hs:1: Illegal parallel list comprehension: use -
fglagow-exts ]

PROBLEM: glagow-exts should be glasgow-exts

If we supply this option, one of the warnings is incorrect:

[ Bla.hs:1: Warning: Defined but not used: y, z ]

PROBLEM: z is used but marked as not used
