Avoid losing info when formatting integers
* doc/lispref/numbers.texi (Integer Basics): Clarify that
out-of-range integers are treated as floating point only when the
integers are decimal.
* etc/NEWS: Mention changes.
* src/editfns.c (styled_format): Use %.0f when formatting %d or %i
values outside machine integer range, to avoid losing info.
Signal an error for %o or %x values that are too large to be
formatted, to avoid losing info.
