I'm really not crazy about this. I have a bad feeling that I'd going to run
afoul of it a lot :(

Why should we specify individual files instead of directories?

[agrieve, 2016/03/15 02:04:02]

Yeah, I'm not 100% set on it either, but I think with a presubmit check it'll be
okay.

Some reasons to do it:
1. The directories were still including
third_party/catapult/catapult_base/catapult_base/bin/reference_build
2. This avoids including files that aren't needed (e.g. python unit tests)
3. There were files missing from the manual list (e.g. appurify)

+required for .isolate files.
