[Help-gnucap] Return status

[Joakim Nilsson]

Hello!

While constructing a makefile for an EDA workflow, I just noticed the
return status of gnucap may be 0 even though an error has occurred.
More specifically, the line:

Q1 3 5 4 npn 1

prints the error:

Q1: can't find: 1

, but the return status is still 0. Since gnucap aborts after this
message, shouldn't the return status be non-zero?
