One comment.  Maybe you can add in the notes that the comment keyword
can be used to write a header and still preserve compatibility with
loadtxt.  This wasn't obvious to me at first, though maybe that's just
me.

Other than that I think it looks like a good first effort towards
making this a better function and I appreciate the attention here.
