[r-t] internal runs

Also in the 90s I seem to remember Patrick Brooke telling me he had 
composed (and rung) a peal containing all 5678s (including internal) - 
maybe plain and little bob.

It was around the same time that I produced this
(5008 plain bob major, 24 each 2345's, 3456's, 4567's and 5678's forwards 
and backwards off the front and off the back, and no 87's at backstroke.)

I don't know whether this was the first peal with this property. 
Probably not, but I wasn't aware of prior ones.

Internal runs are certainly alot less inspiring than external ones, but I 
still like the theoretical challenge of "the 1002"...
