Subject: vis: move file name and word completion logic to a shell script

The shell script should be reviewed for quoting issues, currently
it allows command injections as in:

 $ vis-complete "'; rm -f some-file; echo "

However it is intended for interactive usage and from within vis
it is only ever called with a valid completion prefix.

The file name completion logic now supports nested directories.
