How about extending the syntax to permit specifying multiple elements,
in which case only those will be shown?  E.g., «zstat +uid:gid:mode
./foo» or «zstat +uid +gid +mode ./foo»?  The latter syntax would
necessitate an incompatible change notice in NEWS/README (because «zstat
+mode +foo» does stat("+foo"), exactly as the docstring promises).  The
output of the example invocation would be as follows (assuming -o is
also passed for sanity):
	mode    0100644
	uid     1000
	gid     1000

Looping over the one-element syntax isn't convenient when multiple file
targets are passed.  Ditto grepping the output.

Just looking for consensus on the direction at this point; not planning
to implement this immediately.
