Looks good to me. The new modulo operator needs documentation, and it
could use a pgindent run, but other than that I think this is ready for
commit.

It would be nice to go even further, and replace process_file,
process_builtin, and process_commands altogether with a Bison parser.
But this is definitely a step in the right direction.
