Sorting lines on colour (color for some)

[Francis Nugent Dixon]

Hi from Beautiful Brittany,

Thanks to all you guys (and Jacqueline) for the wealth of suggestions
to solve my little problem. That’s a lot of brain power out there.

I had thought of tacking the colour code onto each line, sorting by
the normal way, and then stripping off the code.

But I knew that someone out there would have a mind-blowing answer  !
I like the regex use.

Thanks again

-Francis
