Help, 2024/12/5. Also correct the timing of the request for the next
call and modify a constant to make the method more robust. To support
the main change, cm_analog_set_temp_bkpt() now reports when a breakpoint
request is ignored, and T(x) values are set before an EVENT call.

VDMOS: concatenate inner node name

Now that checks on actuals and formals have been fixed for X* instances, some older PSpice libraries will not translate correctly in psa mode. This commit removes unnecessary power and ground nodes from X* instances of subcircuits where the nodes are optional. These X* instances occur within the body of another subcircuit which is being translated. MicroCap libraries that we can translate in ngspice do not have such cases. To enable the removal of the power and ground nodes, set ps_global_tmodels=1 in .spiceinit. This is not set by default since an extra pass through the circuit word list is necessary to find the subcircuits whose instances do not require power and ground node removal. Without enabling this feature, errors reporting too many parameters may be reported.

Initial fix for Bug 710 -
...
"The log file appears blank when a VDMOS element is added".
The problen was caused by a crash during sensitivity analysis
caused by selecting parameters for wariation based on their
values. That is not repeatable between passes. The fix is to
remove that code, but it causes many more parameters to be used.

Remove function cp_ccon() and related code. The function modifies
...
the terminal driver's treatment of the control-D (EOF) and escape
keys on Unix-like OSs. But escape has no special meaning, and treating
control-D as a line terminator was probably to prevent unexpected
session exit when connected through a modem without error-correction.
Removing the function allows "ngspice netlist &" to work correctly.
The function was called during initialisation, which caused an endless
loop of job-control stops when ngspice was started as a background process.
