emacs/lisp/calc/calc-ext.el
Jay Belanger d1cb2f7855 * lisp/calc/calc-units.el (calc-convert-exact-units): New function. 
(calc-convert-units): Check for missing units.

* lisp/calc/calc-ext.el (calc-init-extensions):  Autoload
`calc-convert-exact-units' and assign it a keybinding.

* lisp/calc/calc-help (calc-u-prefix-help): Add help for the
"un" keybinding.
