The ccm.cli.tools.merge.*.checkstatus setting
defines whether the exit status of the merge tool must be checked.
If set to true and the tool exits with a non-zero
exit status value, the Rational® Synergy
CLI reports an error message.
Each merge tool preference of the form ccm.cli.tools.merge.type.client has
a corresponding ccm.cli.tools.merge.type.client.checkstatus preference.
Default value: false
