ghc --make sends progress output to stderr
This is a relatively minor problem, but it is really annoying. Running ghc --make generates progress output on the standard error stream rather than the usual standard out. For example, lines such as the following appear on stderr:
[ 1 of 13] Compiling Poly ( tools/mackerel/Poly.hs, Poly.o )
[ 2 of 13] Compiling Space ( tools/mackerel/Space.hs, Space.o )Could you please consider changing this so that progress output goes to stdout and only actual errors go to stderr? Without this, it is much harder to quieten the output from ghc but still see actual errors, and various build system tools incorrectly identify the progress output as error messages.
