Pointer Events pull requests

Hey,
I assume like for TECG we want one of the editors to approve pull requests,
right?  Looks like we don't yet have the automatic notification setup to
IRC (or the list?).

Before I make other changes, I think we should be normalizing line
endings.  Any objections?

https://github.com/w3c/pointerevents/pull/5
The HTML files were checked into GitHub with CRLF line endings. GitHub (and
Git generally) prefers the use of LF in the repo (see
http://adaptivepatchwork.com/2012/03/01/mind-the-end-of-your-line/ for a
great detailed discussion). It should be easy for Windows users to have git
auto-convert to CRLF (eg. "git config --global core.autocrlf true"), but
it's apparently not easy for Linux/Mac users to have Git convert CRLFs in
the repository to LF. I spot checked a few other W3C GitHub repos and the
specs there all have LF line endings.

This is the first non-trivial change in PEWG level 2, so hopefully diffing
past it isn't a big deal.
