Re: Typos in the code and README

(I know Daniel mentioned he'd get to these, but the ScanDirection one
was my fault and I needed to clear that off my mind. I did a few
others while on this topic.)

I'd need to spend more time to understand this.

Daniel fixed in cc59f9d0f.

I wasn't sure if nothing else external could be using this. The macro
doesn't use any fields that are now gone, so I'm not confident enough
to remove it. Can Robert confirm?

Daniel fixed in 88e3da565.

I read that commit message and I agree it's now unused. I just didn't
get any vibes from the commit message that it shouldn't ever be used
again.  Can Tom confirm?

I would say it should be removed.  I just didn't because the commit I
had pending fitted into the "typos" category and this didn't quite
fit.

I've attached a patch with the remainder.
