It has been brought to my attention that I made an error in trying to 
clarify the symbolic use of ["].  Confounding things even further, I 
suppose.  It does, of course, symbolize inches, but in terms of angles, 
it is signifies seconds, not minutes, which uses ['], linearly used for 
feet.

Sorry for any confusion.
