And, boy, did it make a difference!  A quantum leap in readability and
maintainability (and therefore modifiability) of the shell.  It seems to me
that at about V.2 AT&T got serious, and went through *everything*, formatting
the C code, regularizing argument parsing via getopt, and so on.

I think it's pretty fair to say that AT&T concentrated on the user-level
stuff through V.2, while UCB concentrated on the kernel level stuff
through 4.3.
