Subject: [PATCH] "proc is_xschem_file" reports SYMBOL if file contains <=2
 instances of symbols. Need to figure out a different, simple and reliable way
 to recognize symbols that contain a title and/or a "architecture" symbol. For
 the time being reverted to previous state. Thanks to JL for pointing out the
 issue
