Thanks, Ben. The thought did occur to me about the global versus
local, and I explicitly used setl and setg to make foldcolumn=0. The
problem persisted, albeit in a random manner (sometimes I succeeded).
That's when I looked at the help for foldcolumn. The strange thing is
that the documentation says it is local. Is there something about how
to interpret the documentation that I should be aware of?

Thanks for clarifying that "set" simultaneously does a setl and setg.
Always wondered about that.
