Fix delete_incomplete bugs:

1).  On systems I tried, delete_incomplete failed because the line:

< pcmd rm $VVERBOSE -rf "${ddir}/${realincomplete}" || \

should read:

> pcmd rm $VVERBOSE -rf "${realincomplete}" || \

(Is this true of all systems?)

2).  The marker file was not deleted.  Code was added to delete it.

3).  The delete_incomplete code was simplified.
