 I have "wgs84" locations in different dbases, for example:
 "/grassdb/ellas/wgs84" and "/grassdb/global/wgs84".

 I want to "r.proj" something from "ellas" to "global" dbase and I get
 the following error:

 ---
 # working in "global"
 g.gisenv

 GISDBASE=/geo/grassdb/global
 LOCATION_NAME=wgs84
 MAPSET=PERMANENT

 # trying to "pull" data
 r.proj aster_gdem out=aster_gdem_ellas location=wgs84 mapset=PERMANENT
 dbase=/geo/grassdb/ellas

 ERROR: You have to use a different location for input than the current
 ---

 Even though r.proj is meant to re-project data from one location to
 another (= usually different projection definitions) within a dbase, it
 could be used to "pull" data from a different grass-dbase as in my
 example-attempt above.

 This is a bug, ins't it? I suppose the "dbase=" parameter is not checked
 at all in this case (?).

 Alternative solution with respect to the specific example here: allow
 g.copy to copy data from another dbase/location to the current dbase in a
 location with identical name and projection definition of course (?).
