'separator STRING: Change separator for output mode and .import
You can use quotes and backslashes.  For example to set the
separator to space tab space you can use:
.separator " \t "
The setting is automatically changed when you switch to csv or
tabs output mode.  You should also set it before doing an
import (ie , for CSV and \t for TSV).'

    self.separator = self.fixup_backslashes(cmd[0])
