Since CGI.pm 4.05 (2014-10-08), a warning is shown for every gitweb request involving the "h" or "hb" parameters. There is no vulnerability since "add_review_link" only takes one scalar parameter. Force a scalar to prevent the warning in gerrit error log. Bug: Issue 5897 Change-Id: I1b7e6b608af7700225da8625cb749fa12e971591
