(1) We don't check the noninitials; :1 is unambiguously a
keyword, so we don't need to print :|1|.
(2) A keyword with an empty name can be printed just as :,
instead of :||.
These conventions are useful if we pass the S-expression with
these keywords to other Scheme implementations that don't support
CL-style keywords; they would just read those ones as symbols.
