To quote a quote I got from you:
Zero is an enigmatic value. It can mean success (fclose) or failure
(scanf). It can mean black or white. It can mean no permissions (chmod)
or all permissions (umask). It can mean now (setjmp) or later (atexit).
It can mean the beginning (lseek) or the end (read). It can mean myself
(getpgrp) or child (fork). It can mean all (kill's 1st argument) or
nothing (kill's 2nd argument). It can mean 'default' (SIG_IGN) or 'I
don't care' (waitpid) or 'try to guess' (strtol). Indeed 0 lets you talk
to God (setuid). Verily is 0 all things to all people.

My current thought is
* Start counting at 1
* Suppress the dots if there are fewer than the configured max
(rationale: if there are fewer units to program than dots, it will
be done very quickly anyway)
* Have a configurable upper limit, default to 45 (1..9). This will
allow changing the #define to make the dots friendlier to 40
column displays, for instance.
