Thanks, I understood your concern.  I tried the new patch and
confirmed that your MyJediRL can be used as a custom completer by
storing it in a file specified in the PYTHONSTARTUP environment
variable.  This may be the better way to go.

Sorry, I noticed one more thing.  As written in the comments below, it
would be better to use `line-beginning-position' and
`line-end-position' instead of `pos-bol' and `pos-eol'.
