[Gnuplot-bugs] command line not as cool as mysql's: use libreadline

[Dan J. <ji...@ji...>]

I was just going to report a Debian bug when I saw
libreadline
-----------

Yes, the built in readline of gnuplot is bad. However, libreadline
cannot be used instead because it is licensed under the GPL, whereas
gnuplot has special licenses (patches only). Distribution of those
programs linked together is legally impossible but you may rebuild
your own custom package with readline. Please don't file bugs telling
me to use libreadline in gnuplot...

P.S., the docs say
  plot 'file' using 1`" is identical to "`plot 'file' using 0:1`".
but the former gives
  line 0: Need full using spec for x time data
so had to use the latter.
