Subject: modtool: SequenceCompleter has default [] sequence
Fixes #1602, where SequenceCompleter was called from `gr_modtool rm`
without any argument.
Note that the longer-term goal is still to amend the `rm` statement's
code to prepare a good list of candidates instead of reducing the usage
of SequenceCompleter to just enabling readline editing capabilities.
