Ok, will use this text.  But I have more doubts about using (max-char).
What if this .el is compiled on 64-bit, where a larger value of 'max-char'
will be saved to .elc, but loaded on 32-bit.  Will it fail to load such .elc?

Maybe instead of (max-char) it would be better to use the value 't'
to mean no limitation.  Then to check this value explicitly
in the implementation of 'eval-expression-print-format'.
