"port variants" line-wrapping breaks if terminal columns 0

[jxh@…]

My xterms always start out with:

$ stty -a
speed 38400 baud; 0 rows; 0 columns;

and this makes "ports variants dbus" (for instance) wrap its text as though one had actually set COLUMNS=0 in the environment:

$ /opt/local/bin/port variants dbus
dbus has the variants:
   no_root: Run
            the
            DBUS
            daemon
            as
            MacPorts
            install
            user.
  [...]

There is some code that reads this through Pextlib and term_get_size, but it arguably shouldn't take a 0 result as quite real. If it leaves env(COLUMNS) alone, wraplabel, called from action_variants, will do the right thing.

The attached diff shows a suggested fix.

This is Snow Leopard, Mac OS 10.6.

Just for future reference, we prefer unified diffs (diff -u).

Sorry about that. I'm new here. Will attach that as well.
