[nhc-bugs] the format of error diagnostics

Hello, nhc98 would be much more convenient to use if the error diagnostics were compatible with Emacs compile mode. In other words, instead of nhc98 -c -d ../nhc Flatten.hs ==================================== Error when renaming:: Constructor OK used at 833:6 is not defined. it would be nice to have the message appear as Flatten.hs:833:6: Error when renaming:: Constructor OK is not defined.
