Dump code before patching #10
Description
#9 added the ability to dump the patched code to disk. It might be helpful to dump the pre-patched code as well (it can be different than what is in a module's source repo due to people insisting on writing not-JavaScript).
Looks good.
Might be worth dumping code before and after so it's easier to diff the changes!
