[GRASS-dev] Bad map deletion beahviour with external OGR sources

[Benjamin Ducke]

I Think I found a problem with OGR datasources linked
in using v.external.

If I change into a directory with shapefiles and then
issue the following to link in the data in "myShapefile.shp":

  v.external dsn=. layer=myShapefile output=linked_in

And then change into another directory and issue any command
that wants to work on "linked_in", e.g.:
  
  g.remove vect=linked_in
  v.info linked_in

I get:

  ERROR: Cannot open layer 'myShapefile'

But when I change back into the directoy where I used
to be when running the v.external command, it works.

So I think v.external should take care to always link
to the absolute location of the source in the file
system (if I specify "dsn=" as an absolute path,
things work fine).
