Calc history out-of-date

[Michael Welsh Duggan]

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

This may be excessively trivial, but in the interest of
completeness...

The Emacs Calc "History and Acknowledgements" node contains the
following phrase:

"Emacs Lisp doesn't have built-in floating point math, so it had to be
simulated in software.  In fact, Emacs integers will only comfortably
fit six decimal digits or so--not enough for a decent calculator."

This statement was correct when originally written, but has not been
true for some time.  I think the original text should not be changed,
as it is a first-person not from the author to the reader, but a
footnote could be added.  A prototype patch follows:
