port deps / port variants port1 port2 ... does not clear result between ports

[ecronin (Eric Cronin)]

When running port variants with multiple ports specified causes incorrect output for ports with no variants when following ports with variants:

[mrteeny] ecronin% port variants boxbackup; port variants duckytool boxbackup has the variants:

server darwin

duckytool has no variants

[mrteeny] ecronin% port variants boxbackup duckytool boxbackup has the variants:

server darwin

duckytool has the variants:

server darwin

either ports with no variants should explicitly clear the variable in question, or variants should clear it itself between iterations.

[ryandesign (Ryan Carsten Schmidt)]

On 2006-11-26 a variant was added to the duckytool port, so the above example no longer works. However using cogito instead of duckytool still shows the problem:

Output correct:

$ port variants boxbackup; port variants cogito
boxbackup has the variants:
        server
        darwin
cogito has no variants

Output incorrect:

$ port variants boxbackup cogito
boxbackup has the variants:
        server
        darwin
cogito has the variants:
        server
        darwin

Note also that "port deps" suffers from the same problem as "port variants":

Output correct:

$ port deps cvsgraph; port deps cvslock
cvsgraph has library dependencies on:
        gd
cvslock has no dependencies

Output incorrect:

$ port deps cvsgraph cvslock
cvsgraph has library dependencies on:
        gd
cvslock has library dependencies on:
        gd
