Comment (by gracjan):

 I agree that this change throws away useful information while keeping in
 not so useful one.

 I would do it simpler though:

 If verbose, show information as it used to be show, with full paths.
 If not verbose, show just module name.

 Note that haskell-mode filters out everything after module name and this
 is expected behavior by newbees or when smaller projects are compiled. For
 more complicated projects hvr and other can increase verbosity level.

 I would also postulate to *not* add new flag with such low marginal
 utility and just use the existing verbosity level for this purpose.
