Comment:
I really think we should do this, given the number of times beginners get
tripped up by the fact that "ghc Setup.hs" gives linker errors, for
example.
So here's a draft plan. Can anyone forsee any problems?
* If the command line contains any Haskell source files and ''no'' mode
flags, then we use `--make` rather than batch processing
* for this purpose, `-c` counts as a mode flag, otherwise build systems
break
Strange things arising:
* If you want the no-linking behaviour with `--make`, then you have to
say `--make -c` explicitly
* The existing behaviour of `ghc Foo.hs` is not available, instead you
get `ghc --make Foo.hs`. The latter is usually the right thing, but If you
actually wanted the former behaviour (I'm not sure why), you now have to
do it in two steps: `ghc -c Foo.hs; ghc Foo.o`.

which is in the same bit of code, so do them both at the same time.
