v.out.ogr does not export features when 'dsn' AND 'layer' options are given

[dylan]

# does not export any features, # complaining that they don't have categories v.out.ogr -c in=bugsites dsn=some_folder layer=new_shpfile

# exported expected features v.out.ogr -c in=bugsites dsn=new_shpfile

This must be related to some magic associated with flag/option parsing.

As defined in the man page:

layer=integer
    Layer number
    A single vector map can be connected to multiple database tables. This number determines which table to use.
    Default: 1

So your use of layer is incorrect.

Also, note that the default of type= is 'line,boundary', so if you are trying to export areas, you will have to explicitly set type=area.

Closing this bug.
