bpo-29557: Remove abiguous line in binhex docs

[davidwilemski]

"appears to not work in all cases" does not inspire confidence in this
module. I can find no context for what bug this was referencing so it
should be removed.

It appears this comment was from the original documentation for this function in 1995 but the commit also does not include any context regarding a bug: https://hg.python.org/cpython/rev/3911d4a89ab0#l4.40

There was a bug fixed in the binhex function in 2009 but I have no idea if this was the bug that this documentation line was referring to: https://bugs.python.org/issue6369

I see no other open issues for binhex in the issue tracker so I believe this line should be removed until we have a concrete bug report that can be referenced by the documentation.

Thanks for the PR! I think your analysis looks correct. However, it would be nice to record your research on bugs.python.org. Also, we can get more feedback from other core developers since not all of them subscribe to the GitHub repository.

Sure, I wasn't sure where to draw the line for a trivial issue so didn't create a bug up front. I've created one now: http://bugs.python.org/issue29557
