That's useful, but I think it's not as good as changing the module
headers. As you say, that will choke on some modules; it's an extra
step; and by removing comments entirely, one can no longer investigate
any duplication in *comments* as well as code (I'm sure copy-pasta of
comments exists, even if only in the module headers.)

And I don't entirely understand the reticence to use multi-line
comments. Weren't they intended for exactly these sorts of situations,
massive comment blocks spanning entire pages? How exactly are a couple
hundred prefixed '--'s superior to a {- -}?
