BUG: 'port variants' has innacurate output with multiple targets

[elcascador@…]

Just have a look at the output of 'port variants package1 package2'. First I request the list of variants of 2 packages, seems qt3-mac and pixen have the same variants. But that's wrong, pixen has no variants.

In /opt/local/bin/ports line 1720 it seems that the variable 'result' doesn't get cleared correctly during the search using 'dportsearch'. I'm not a tcl coder so I can't fix it, sorry.

chri@aether ~/Data/MacPort 
 Sat 07 Oct 21:12 $ port variants qt3-mac pixen           
qt3-mac has the variants:
        mysql
        ipv6
        darwin
        darwin_8
pixen has the variants:
        mysql
        ipv6
        darwin
        darwin_8
chri@aether ~/Data/MacPort

pixen has no variants

This problem is very closely related to #8229, perhaps the same cause.

Thanks for the report. This should be resolved in r19992. Please verify.
