K&R 1st edition Reference Manual section 2.2 mentions 8 (including
underscore) as the number of significant characters, though names can
be longer. External names are more restricted: it has a table of
limits for external names for various targerts. PDP-11 is 7 chars,
Honeywell 6000 is 6 chars (with no case distinction).
