Subject: [PATCH] inpcom.c, workaround for "#307 define problems with the
 Modelname "mname" with Subcircuits"

a diode model named "1smb4148" could not be found
  because it was dropped in `comment_out_unused_subckt_models()'

as a work around the function
  is_a_modelname()
is extended to accept an additional pattern which does match "1smb4148"

Thanks to Martin who submitted the bug report here:
