Unzipping Mac executable files with revZip - revisited

[Pete Haworth]

I ran into this once with Time Machine.  I restored an iPages file from a
backup and it brought it back without an extension and treated it as a unix
executable.  Even more ironic that Time Machine can't restore a file from an
Apple application properly!
