the saveVersion.sh script sometimes fails to extract SVN URL
------------------------------------------------------------
Key: HADOOP-7471
URL: https://issues.apache.org/jira/browse/HADOOP-7471
Project: Hadoop Common
Issue Type: Bug
Components: build
Reporter: Alejandro Abdelnur
Assignee: Alejandro Abdelnur
When using an SVN checkout of the source, sometime the {{svn info}} command
outputs a 'Copied from URL: ###' line in addition to the 'URL: ###'.
This breaks the saveVersion.sh script that assume there is only one line in the
output of {{svn info}} that contains the word URL.
