NetBSD/distrib/utils/sysinst/upgrade.c
dsl 3a2118e931 A load of usability fixes mainly to network installs.
I've made the error retry loops go back as far as the input menus.
Split all the pathname inputs into 2 pieces (base directory and set directory).
Reduced the size of some fixed strings.
Stopped the install aborting if ftp can't find a set (eg the X ones).
The French and Polish transations don't differenciate between Base_dir and
Set_dir - but that can be fixed later.
