Comment (by NeilMitchell):

 Actually, in Windows I believe it is GHC that does the wildcard expansion
 - not the shell. Either way, the intention of :main is to test the program
 as though you were running it from the command line, which means that
 getArgs should really do the expansion.

 I am happy for this to be a Windows only fix, or for it to use the Windows
 expansion GHC defaults to on all platforms. For Unix you could always do
 system ("echo " ++ args) or some similar clever shell trick to expand the
 arguments.

 This bug was seriously confusing to a beginner (on whose behalf I'm
 reporting this).
