Bad error message for missing module in --make
GHC --make uses getImports to find the imports of a
module. It has two bad flaws
a) it's a total hack, parsing the file character by
character, which is really slow. We though it stopped
after the import statements but it doesn't; it chunters
through the entire file
b) It does not record line numbers, so if the imported
module does not exist, there is no decent error message
We have a plan; this bug report makes sure we don't
forget.
