On the beginning we have empty "barcode" parameter for this form, but that not taken into account in regular expression warning emitted: "Use of uninitialized value $barcode in substitution (s///) at /usr/share/koha/intranet/cgi-bin/circ/renew.pl line 47." in renew.pl
Fixed by making $barcode to become an empty string by default.
To reproduce:
1) Head over to the "Circulation -> Renew" page.
2) Check intranet-error.log there will be a warning "Use of uninitialized value $barcode in substitution (s///) at /usr/share/koha/intranet/cgi-bin/circ/renew.pl line 47".
3) Apply the patch, refresh the "Renew" page.
4) Ensure that the new "use of uninitialized value" warnings didn't appear in the console.
