Note the comments "(if null, write ~/.history)"! This is supported in the original C API but in Haskell the filepath cannot be null. In the best case it can be empty string. Either the type signatures have to be changed to accept (Maybe FilePath) or the comments have to be changed because the Haskell binding currently doesn't support this functionality.
If writing to ~/.history is useful then Maybe FilePath makes sense to me, as ~/.history is a bit fiddly to work out yourself. However, it doesn't sound that useful to me, as then all applications would trample over each other. If you want to propose that it uses Maybe FilePath then you'll need to follow http://www.haskell.org/haskellwiki/Library_submissions; otherwise I'll just fix the comments. Thanks Ian
