//chrome/common means the same thing and is shorter

[cjhopman, 2014/10/23 00:15:48]

For these pointers in GYP to the GN target, I've been avoiding the implicit
target to make it easier for people who are editing gyp and need to update the
gn file but might not know about the implicit target.

Maybe we can assume that people know that //chrome/common:common ==
//chrome/common, though. I don't really feel too strongly about it, anyway, so
let me know if you think we should stick to the shorter one.
