Hmm, that might be OK.  The documentation is a bit inconsistent.  If we choose 0 
to mean 0 lines go to the history file.  How do we set the history to 
"unlimited"?  The answer is "unset history".  That's a bit strange in the sense 
that the documentation says:

  The value <int> indicates the value of history size when leaving gnuplot.  It
  is used for truncating the history to at most that many lines.  The default
  is 666.

[snip]

  `unset history` will set history operation to its default settings: no history
  truncation at exit and thus allow indefinite number of lines, `condensed`, and
  `numbered`.

In one case the default is 666 in the other it is indefinite.  There is no "set 
history inf" or anything like that.
