Re-enable standard hlint warnings
Commit 5a1e31b4 (Add infrastructure for, and two extra hlint rules)
was intended to add two extra hlint rules, but I didn't realise at
that time that "--hint" when first used overrides the built-in
lints. As such, since then we were basically running with just those
two rules, which resulted in many uncaught warnings/errors.
This patch fixes that (by importing the standard lint rules in our
custom hints file), and then goes to fix all the warnings that a
current hlint gives me. Compared to our current style, we have just a
few additions:
- zipWithM instead of map foo . zip …
- 'exitSuccess' instead of 'exitWith ExitSuccess'
- more uses of '.'
Additionally, we have to silence a case where hlint doesn't realise
why we are using '\e -> const (return False (e :: IOError)' instead of
just '\e -> return False' or even 'const (return False').
One warning that is generated by hlint ("Use void") can't be fixed
until we deprecate GHC 6.x, as only GHC 7 has the 'void' function in
Control.Monad.
