Subject: [PATCH] Improve perl.req script

This commit 0d5929ba5eabadec49273bb090ba9158dfccc30c tries to ignore
"use" and "require" within multi-line print statements that start with
line like this "print <<EOF" but it incorrectly parses lines in
following format "print <<EOF unless $o" and every "use" or "require"
below this line to the end of file is ignored. That causes that some
requires which was previously found are not found now. This commit
fixes this problem (#1268021).
