Add a fix for Long-standing problem with VMware. Described in below links:

https://communities.vmware.com/thread/107230
https://communities.vmware.com/docs/DOC-11677

Basically, ignore the ``function 62'' and ``function 63'' interpretations
of the left/right command key when we're in the lengthiest portion of the
installation (initiated by the `auto' module).

The net effect is that you can now (once you've started the installer from
the media) escape the VM without prematurely terminating the current action
due to spurious escape sequence.
