Subject: [PATCH] Advice that /usr/bin/vi link was removed.

Upgrading from 14.2 to 15 some packages (elvis, vim, nvi) may remove
the symlink /usr/bin/vi, but only the nvi package automatically
recreate it.
The slackware 15.0 installer uses /var/lib/pkgtools/setup/setup.vi-ex
to allow user to choose which editor to use.
