I just committed some spring cleaning - removing checks and conditional
code for grass 6 and removed checks and the if-checks for grass 7 code.

The examples are completed successfully.

One think I realised: I had a complete quitting of R when I had set the variable

,----
| export GDAL_DRIVER_PATH=/usr/local/lib/gdalplugins
`----

when executing the command

,----
| bugsDF <- readVECT("bugsites", ignore.stderr=TRUE, mapset="PERMANENT")
`----

No error message, nothing, just back in GRASS. - never sen this before.

I do not know if this is caused by a not with grass7 compiled plugin or
why as I usually do not use the plugin.

Cheers,

Rainer
