Comment(by simonmar):

 On Windows it is true that the program does globbing, but that's because
 Windows made an astonishingly bad mistake here.  On Windows you can even
 use globbing in the arguments to `rawSystem`, but only if the program
 you're invoking supports globbing.

 Would you expect `:main <foo.txt` to work? I expect not. There's a
 slippery slope here, where we could end up implementing more and more
 shellisms in `:main` (and which shell syntax?). On the other hand, we
 already implement a little shell syntax, in that we do word-splitting and
 quoting on the arguments to `:main`.

 One interpretation of `:main` is that it is nothing but shorthand for
 `withArgs xs $ Main.main`. This interpretation I like, because it is easy
 to explain, and is platform-independent.
