c/ch2/tri.c
is an example. Make this uniform so that
$ ./program -help |head # determine that "prg_" is prefix
$ ./program -help |grep prg_ # list the options with this prefix

Then document this feature in Chapters 2 and 3 where it will first be used.
I still need to go through and make this uniform.
I believe this is done enough.
