 As I said; since you are the author of the layer name mechanism, I was
 leaving this to you for checking. ;-)

 Does the layer name necessarily have to correspond to the map name ?
 AFAIU, layer names are mostly used for direct OGR access. Internally in
 GRASS vector format, it's the layer number that is used. So I'm not sure I
 would call this a bug, but potentially an enhancement request for
 aesthetic reasons.

 The same actually happens when you copy a map:


 {{{
 g.copy vect=roadsmajor,roads
 Copie vector  vers  dans le jeu de cartes
 courant
 GRASS 7.3.svn (nc_spm_08_grass7):~ > v.db.connect -p roadsmajor
 Vector map  is connected by:
 layer <1/roadsmajor> table  in database
 
 through driver  with key 
 GRASS 7.3.svn (nc_spm_08_grass7):~ > v.db.connect -p roads
 Vector map  is connected by:
 layer <1/roadsmajor> table  in database
  through
 driver  with key 
 }}}

 I'll add a diff that seems to do the trick for me, but I'm not sure that
 this is really needed, nor if it is desirable. Martin introduced the
 layers names so he should probably have a look at it.
