ports-mgmt/portconfig surprize

Folks,

  somebody got the idea to replace the dialog4ports options
configuring interface by something named 'ports-mgmt/portconfig'.
(And they did not even find it worth mentioning this in the
UPGRADING file.)

Now this one looks terrible, the screen is garbled, and it is
quite unintellegible which line is currently entered.

What is happening:
I am starting a shell script. That fires up a bhyve. In the bhyve 'make'
is run with stdio connected to the second COM.
In the script on the host, bhyve is put in background, 'cu' is started
and connected to that second COM. There the dialog appears.
Since the script on the host is run from remote, it is run within
tmux.
Point is: it did work before.

disappointed,
PMc
