But that makes it seem like it's a property of the data file [*].
It isn't.  It's a question of mouse interactions and hot keys.
That's why I suggested "set mouse ..."

Actually, I'd much rather have a mechanism that *was* tied to
specific data files.  That way you could mark a particular
data file as volatile, or not re-readable.  That would free me
from having to make this quick refresh mode work for all 
possible mixtures of plots simultaneously, which is a headache.
But so far I have not figured out a way to do that.

The decision is made at a higher level:  either we re-parse
and re-execute the plot command line, re-reading files as we go,
or we skip that whole operation and go with what's already in
the plot data structures.  It's all or none.

[*] In fact it works the same way for functions, although that's
an unintended side-effect.
