Is "sqlite3 CLI shell" the 'sqlite3' binary that is already installed by 
the sqlite3 port?

It's well known that Tcl 8.6 bundles all of sqlite3. Probably fine to 
remove or rename this script though.

There's no standard scheme. The usual approach is to append the name of 
the port to one of the files.

You think right. :)

I would think a separate port (or subport) would be better. A 
non-default variant would not be available as an archive, and I don't 
like the idea of adding a Tcl dependency to sqlite3 by default.
