(calc-embedded-firsttime, calc-embedded-firsttime-buf,

calc-embedded-firsttime-formula): New variables.
(calc-do-embedded): Use calc-embedded-firsttime,
calc-embedded-firsttime-buf and calc-embedded-firsttime-formula to
determine whether or not to run hooks.
(calc-embedded-make-info) Set calc-embedded-firsttime-buf and
calc-embedded-firsttime-formula appropriately.
Set calc-embedded delimiter variables according to mode.
