zdump was designed to be independent of the underlying implementation. It 
doesn't know about file names. All it does is set the TZ environment variable 
and go. There is value in keeping zdump simple like this, as it provides a way 
to test any string that you could set TZ to.

We could add an option to zdump which would mean "prepend $PWD to arguments not 
beginning with slash", or something like that; but I suspect it's hardly worth 
the trouble, as anybody who would know about the option would also know about 
$PWD and can just prepend it themselves.
