New Revision: 105

Modified:
   buildrom-devel/bin/fetchsvn.sh
Log:

This fixes a subtle bug in the fetchsvn.sh script. Because of the use of an
exit statement in a subshell, the script did not abort when an svn update
failed, leading to tarballs that claimed to be some svn revision but were
really some other revision...

This is a trivial patch.
