Thanks for the info, but how do you set the filetype when you create the buffer?
That's assuming you're not running Vim from a command line and so can pass the
filename when you start the program. Uh, OK, nevermind. The obvious occurred
to me when I wrote that line. I didn't realize that :tabnew took args.

That never occurred to me. Quicker than manually setting the filetype.

Cool. I'll keep that archived but hopefully I can train myself to just name
the file when created.
