**BUG**
Concise problem statement:
Running a TL081EE simulation with a pasted-in edited copy of the TL081EE subckt is broken.
Pasting in and editing a copy of the TL081EE and other in-house opamp or comparator subckts used to work.
Please see:

Steps to reproduce the problem.
1) Draw a schematic with the 5 pin Opamp and change the part name to TL081EE;
2) Copy the subckt for the TL081EE from the netlist for this schematic;
3) Paste it into this schematic;
4) Change the name of the subckt to make it different from TL081EE;
5) Paste in a copy of the LM108 netlist from:
https://easyeda.com/example/LM108_using_a_pasted_in_subckt-afLFztL3X
and set it to "spice";
6) With the pasted-in TL081EE_edited subckt set as "comment", do:
Ctrl+R then select "Transient" then click "Run" to run a time domain simulation.
The sim runs OK.
7) With the pasted-in TL081EE_edited subckt netlist on the right set as "spice", do:
Ctrl+R then select "Transient" then click "Run" to run a time domain simulation.
The sim does not run and the simulation results window shows:

The LM108 netlist shows that this is not a general problem with all pasted-in subckts.
The problem seems to be something to do with the copied and pasted version of the TL081EE subckt.
* Pasting in and editing a copy of the TL081EE and other in-house opamp or comparator subckts used to work.
Has there been a change to the way some character or string in the schematic editor that now breaks schematic parsing of the pasted in netlist?
