Fixed a bug in the tokenizer for the case the last token has an open quote and extends past point.
`bash-completion-process-tokens' now explicitly returns the "stub".
The argument END to `bash-completion-get-token' is now optional (as is called LIMIT).
`bash-completion-comm' and `bash-completion-generate-line' now take an extra argument STUB.
Untabify.
Use `completion-in-region' now with all the advantages (completion styles!) this brings.
