Subject: [PATCH] Remove the setting of sourceid from bf_vm(), as bf_vm()
 really has no clue.

Set sourceid to 0 when booting, which is the correct setting for stdin.

Set sourceid to an arbitrary fd when include'ing, preserving and restoring
the previous sourceid. This is possibly broken(), as 0 is a valid fd. Maybe
we should +1 to this value.

This fixes the version problem widely reported.
