Bourne's sh was written in a pseudo-Algol-68 by using the C
preprocessor, and indeed sh's input language is inspired by Algol 68.
If there hadn't already been an `od' command, the while loop would be
`while list do list od'.  The System V developers eventually took out
the Algol 68 macros in the source.  I think the first released version
of sh without the macros was the SVR2 shell.
