gEDA-user: opinions on move-line-to-layer via removal?

[Ben Jackson <ben@xxxxxxx>]

PCB notices if you use 'move line to layer' on one segment of a trace
and creates vias as needed to keep that trace connected (at least at
the ends, it doesn't notice if you made a big 'x').

If you move a multi-line trace to another layer piece by piece, you end
up with unnecessary vias.  I see three courses of action:

1)  Leave it as is, extra vias stay, user deletes if they want.

2)  If you move a line to the same layer as a line it was connected to
by a via (and no other features on other layers are electrically connected
to the via) then the via is removed.

3)  As in (2), but the via-creation code is changed to set AUTOFLAG (so
the via is "created by the autorouter") and only vias that were auto-
created in this was are removed (other rules same as (2)).
