Need RlwrapFilter in python about rlwrap HOT 3 CLOSED

Great - thanks! Of course a python version is feasible (or a C, Haskell or Cobol version, for that matter...) I'll have a good look at it, and will try to incorporate it in the next rlwrap release!

Hans, thanks a lot for merging and improving it!!!

@hokuda: Merging: done. Improving: hmmm, I'm not that fluent in python. Feel free to change things. Especially moving from bytes to strings (and back) is fraught with dangers. rlwrap, like most Unix commands, is completely coding-agnostic, and only ever sees streams of bytes, which it never really inspects. Filters look at the content of those streams, and will want to work with strings ("capitalize Every Word In The Prompt >")

A good (if rather rough) test is rlwrap -z null.py cat /dev/random . With errors="strict", the default setting, decode() will stumble on the random bytes, and the filter will die.

Decoding with errors="ignore" seems to work well, until now.

Again, thanks for the excellent work!
