You're welcome - I'm glad it worked.
Here's a version with the changes you suggested. The "thing" to send
when there's no active region (i.e. selection) is configurable,
with the current line as the default.
Let me know if it's what you have in mind.
By the way - is this useful for others? If so I could release it on e.g.
MELPA.
Best,
John
