Subject: v.patch: -a(ppend) issues

Platform: GNU/Linux/x86
grass obtained from: CVS
grass binary for platform: Compiled from Sources
GRASS Version: 2006-09-23

$ v.patch -e -a input=map1 output=map2

Error: option <output>: <map2> exists.

Should v.patch in -a(ppend) mode automatically set the --ovewrite flag?

It kind-off works:

$ v.patch -e -a input=map1 output=map2 --o

But leaves the output vector in a somewhat strange state - it is OK for Grass commands (v.digit, v.info -c) but QGIS (current SVN head) complains about it that "No layers available in this map". After I v.build this vector, QGIS accepts it.

v.build helps, but it shouldn't be required. v.patch should output a valid vector. Or maybe this is QGIS fault?

What do you think Radim?
