Netiquette deals originally with USENET, not Web-based messaging forum 
like this one.

And given the level of severity the spamming problem has reached, I'm 
afraid offring a free-for-all plain email address must be considered a 
dangerous thing to offer these days.

I fully second Ethan on that.  Note that if you don't subscribe, all 
submissionss to gnuplot-beta will be put on hold until an admin (i.e.: 
myself) OKs them.

What exactly do you mean by that?  Do you propose gnuplot should
backup all data it receives from a redirected stdin to a disk file?
I really don't think that's a good idea.  Caching it in memory, maybe, 
but not to disk.

Unfortunately, not quite.  Not if "fast" datafile reading (which doesn't 
keep all columns of a single line, must less the entire datafile) is in use.

I think it would make more sense to change the meaning of

	plot '-', ''

from being equivalent to

	plot '-', '-'

(if that's what users wanted, they only have to put in the missing '-') 
to being equivalent to the

	plot '-', '='

proposed here.  I really don't think we need another special filename 
for this.
