[GRASS5] dglib: subtle differences

[Markus Neteler]

Hi,

while going on with the clone detection, I found that

dgl_initialize_V1() and dgl_initialize_V2()

in 
 lib/vector/dglib/graph_v1.c
and
 lib/vector/dglib/graph_v2.c

set pgraph in a slightly different way.

Should this be syncronized (to V1 or V2)?
