add an additional check in MULTI_INSTANCE mode for a more obvious error message
If the user enabled multi_instance mode but didn't create /etc/tor/enabled he gets a unclear error message about file "*".
This additional check should make it more obvious whats wrong.
Proposed chage: Add the following check in line 210:
if ! ls $CONFDIR/*.torrc > /dev/null 2>&1 then echo "torrc file(s) missing in $CONFDIR" exit 1 fi
