I'd recommend putting these in a test namespace, either under remoting or
remoting::protocol, to avoid risk of clashes w/ production code names.

Done.

These should be EqualsKeyEvent, since we no longer support non-USB-style
keyboard input, besides the text events, below.

Done.

You mean in all tests, here and below?

Oops, this is me trying to be smart about keeping original comments but ended up
being cruft. Same for the matcher below.
