Poor parse error message

[NeilMitchell]

The following snippet

main = print $ "hello" ++ "world
-- any random junk that goes here gets added onto the character count
-- and the quote ends it with some garbage " module

Gives:

Sample.hs:1:141: Parse error: module

The character count is crazy (there is no character 141 on the first line). In addition if I remove the module then it passes the parser, but GHC fails on it.
