nit:  Fix indent.

This comment is practically illegible.

To clarify:  A bunch of lines are missing asterisks, it uses a random HTML line
break, and it's not consistently indented.  Even if all that were fixed, I'd
probably have no idea what it means, of course.

You can actually get rid of these annotations, chromium has its own that serve
the same purpose (configuring proguard)

The |UsedByReflection| annotation has not been used in Chromium before.
Dmitry, do you know whether it is necessary (I did find that it doesn't work
without it), and whether it could be replaced by some other annotation like
|UsedByNative|
(https://code.google.com/p/chromium/codesearch#chromium/src/base/android/java/...

[Charles, 2014/03/07 21:31:15]

These should probably be replaced by Chromium's proguard annotations.
