Last day to vote/reject on proposed EOL names

[Ian Clatworthy]

Thanks to everyone for their thoughtful emails on picking
the right names for our EOL settings. Here's my latest
thinking - the names will be upwardly compatible with
those used for svn (except for cr which I'm not planning to add):

* native
* lf
* crlf
* exact
* native:crlf
* lf:crlf
* crlf:crlf

In general, wt-format[:repo-format] where the default
repo-format is lf. I'm happy to change the separator to -, +, / or
something else but : seems as good as any.

I'm planning to land EOL support into bzr.dev with those names
24 hours from now. If anyone objects, here's your last chance
to say why.
