Sure, but it is slightly confusing because...

Your previous email pointed out a problem with 'datafile' reread on ARM 
at a particular instant.  There would then need to be something 
analogous to '-' and '--' but for data files.  OR, the default for 
datafiles could be to buffer the data (no easy task given gnuplot wasn't 
built that way from the ground up).  But if the default for datafiles is 
to buffer data, then '--' becomes analogous to 'datafile' as the default 
behavior, and '-' becomes the special case.

With a mode switch, there is a bit less confusion, but that too has its 
drawbacks.
