* calculator.el (calculator-standard-displayer): Fix bug in use of

`calculator-groupize-number'.
(calculator-funcall): Fix broken `cl-flet' use by moving it into the
`eval' code, so it works in v24.3.1 too.
(calculator-last-input): Comment to clarify purpose.

Also add back a ChangeLog blurb for previous commit 2014-06-15T04:52:34Z!eli@barzilay.org.
