 As [https://lists.osgeo.org/pipermail/grass-user/2016-October/075244.html
 reported] by Dave Roberts and Helmut Kudrnovsky on grass-user:


 {{{
 g.copy vector=firestations at PERMANENT,myfire
 v.category input=myfire at user1
 layer=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25
 output=myfire_manylayers option=transfer
 v.db.addtable map=myfire_manylayers at user1 layer=2
 [...]
 v.db.addtable map=myfire_manylayers at user1 layer=25
 }}}

 Gives the following output when queries by v.what:


 {{{

 d.what.vect and thus the GUI query are also affected.

 The attached patch is an attempt to solve this for v.what. Please test.
