dig for error reason in Skipping section 'Extended Summary' in 'scipy.io.matlab._mio5'

[Carreau]

I've put an assert here:

/Users/bussonniermatthias/dev/papyri/papyri/gen.py:1608 in     
 prepare_doc_for_one_object                                    
                                                               
   1605 │   │   │   │   │   blob.content[section] = Section([],
   1606 │   │   │   │   else:                                  
   1607 │   │   │   │   │   tsc = ts.parse("\n".join(data).enco
 ❱ 1608 │   │   │   │   │   assert len(tsc) in (0, 1), (tsc, da
   1609 │   │   │   │   │   if tsc:                            
   1610 │   │   │   │   │   │   tssc = tsc[0]                  
   1611 │   │   │   │   │   else:                              

I don't remember what this is used for.
