Nathan Whitehorn 36ddc86874 Prevent the set -e from mk-osreldate.sh from propagating into newvers.sh.
This would cause detection of old versions of SVN to cause fatal errors
instead of being caught and handled, which would make the build fail if
the tree had been checked out with an older version of SVN (e.g. 1.6).
