Consecutive tran and ac simulation may lead to gross errors
...
when TC or scale is used on the instance line of C and L.
Reason is the missing reset when CKTtemp is called once during each
simulation command. TC or scale is then applied again and again,
a reset is missing.
This patch adds a reset, i.e. the capacitance or inductance is
reset to its instance value in a call to *temp. It fixes bug#594.
Command 'alter' has been tested.
Resistance has not been tackled by this bug, because the line
here->RESconduct = here->RESm / (here->RESresist * factor * here->RESscale);
differs from
here->CAPcapac = here->CAPcapac * factor * here->CAPscale;
in that there is no accumulation of correction factors with here->RESconduct
