I'll accept this because it works and is mostly fine, but there's a couple of minor inlines.

src/lint/linter/ArcanistXHPASTLinter.php
49	Just a though (not really related to this diff), but whenever a new rule is added, I think that the output of `getVersion` and `getCacheVersion` should probably change as well.
109	Also note related to this diff, but these strings should be wrapped in `pht`?
1971	Do you need keys here? Wouldn't `foreach (array($prev, $next) as $wtoken) {` achieve the same thing?

This revision is now accepted and ready to land.May 27 2014, 11:08 PM

Bump verison.
We should probably pht() everything at some point.
To be completely correct, the rule for prev should disallow newlines (i.e., $a\n.$b is not conventional), but that's kind of complicated and I haven't seen anyone doing it so I didn't bother yet.
