When I run 'ghc -e :etags' on Haskell files, many identifiers have their first characters duplicated in the TAGS file, which causes the tag search to fail. Removing these extra characters by hand produces a valid TAGS file. -e :ctags does not seem to have the same problem.
I am attaching a Main.hs and a TAGS file which show the problem.
