That's why I said you have to remove the '$'s above.  Actually to do it
properly every project should have its own form of Id tags, like $GHC:
.... $, which would avoid this problem.

No, but I can easily imagine eg. hslibs/hssource/HsParser.ly might be
included in someone's Haskell compiler.

Feel free to remove them on a lazy basis when they are obviously
unnecessary.
