[Mimedefang] Example filter bad_ext not blocking .js

[Alberto.daSilva at rmb.co.za]

Greetings,

I was looking at the bad extension list in mimedefang-filter

# Bad extensions
$bad_exts
= '(ade|adp|app|asd|asf|asx|bas|bat|chm|cmd|com|cpl|crt|dll|exe|fxp|hlp|hta|hto|inf|ini|ins|isp|jse?

lib|lnk|mdb|mde|msc|msi|msp|mst|ocx|pcd|pif|prg|reg|scr|sct|sh|shb|shs|sys|url|vb|vbe|vbs|vcs|vxd|wmd|wms|wmz|wsc|wsf|wsh|\{)';

Should this be
...isp|js|jse|lib...
