I was going to do that, but you end up eliminating a lot of clone
possibilities as you'll get an EDID mode on one monitor that exactly
matches a VESA mode on another. Take a look at the history of the
randrproto.txt file; it's been there and been removed already.

I decided that cloning was more important than learning minor details
about where a mode happened to come from.

In this case, as the mode is user-created, no monitor will ever use it
without being told explicitly, so I think it's OK to have a
distinguishing mark.
