Thanks Drew, that’s working very nicely, and thanks for the
speediness! :)

How can I make the line-length of the complete buffer to be 100
please? Again toggling back and forth with 74.

I'm writing a latex document, and 74 seems so short whilst I'm in
the thick of it, so I'm wanting to try out 100.
