 # file to your new one or GN won't know about it.

Okay, Brett and I got a chance to confer, and his concern is that the comment in
line 738 is not necessarily clearly to a non-Blink person, who may not know what
"the layout tests" are or why they aren't just a GN target that could specify
these dependencies directly.

So, let's change this to:

# NOTE: The following deps are needed to run the layout tests (run-webkit-tests)
but there is no GN target for the layout tests, so we need to specify the
dependencies here instead.

or something like that.

Done.
