 in a vector with multiple cat per point (in this case Point Id=3 has
 4 cats:
 [(layer=1, cat=311),(layer=1, cat=312),(layer=21, cat=321),(layer=2,
 cat=322)]

 while v.what gives a correct output:


 {{{
 v.what -a -g map=test at cavriago layer=2 coordinates=2.0,0.0
 East=2
 North=0
 Map=test
 Mapset=cavriago
 Type=Point
 Id=3
 Layer=1
 Category=311
 Driver=sqlite
 Database=D:\GIS_db\Gauss_Boaga\cavriago\sqlite.db
 Table=test1
 Key_column=cat
 cat=311
 t1=311
 t2=
 Layer=1
 Category=312
 Driver=sqlite
 Database=D:\GIS_db\Gauss_Boaga\cavriago\sqlite.db
 Table=test1
 Key_column=cat
 cat=312
 t1=312
 t2=
 Layer=2
 Category=321
 Driver=sqlite
 Database=D:\GIS_db\Gauss_Boaga\cavriago\sqlite.db
 Table=test2
 Key_column=cat
 cat=321
 l2=321
 l3=
 Layer=2
 Category=322
 Driver=sqlite
 Database=D:\GIS_db\Gauss_Boaga\cavriago\sqlite.db
 Table=test2
 Key_column=cat
 cat=322
 l2=322
 l3=layer2
 }}}

 vector_what makes a mess (It returns a single dictionary mixing up first
 cat -> 'Category': 311, 'Layer': 1
 and last cat -> 'Attributes': {'l2': '322', 'l3': 'layer2', 'cat': '322'}

 {{{
 from grass.script.vector import vector_what
 vector_what(map='test', coord=(2.0,0.0), distance=0.0, ttype=None)
 [{'Category': 311, 'Map': 'test', 'Layer': 1, 'Key_column': 'cat',
 'Database': 'D:\\GIS_db\\Gauss_Boaga\\cavriago\\sqlite.db', 'Type':
 'Point', 'Driver': 'sqlite', 'Table': 'test1', 'Attributes': {'l2': '322',
 'l3': 'layer2', 'cat': '322'}, 'Mapset': 'cavriago', 'Id': '3'}]
 }}}

 This bug influences "Query result" dialog in wxGui while "Aggiornamento
 attributi" in vector editing works correctly.
