Re: Touchup of history.c

[Daniel J S. <dan...@ie...>]

I've noticed that currently for --with-realine=builtin on CVS the history stack 
will be truncated upon add_history().  E.g.,

gnuplot> history
     1  set his 6
     2  his
     3  plot x
     4  plot x*x
     5  history
gnuplot> set his 2
gnuplot> foo = 2
gnuplot> his
     1  foo = 2
     2  his
gnuplot>

The GNU readline compilation doesn't do that.  Truncation is only done when 
saving to file.

Which way should history behave?  (I'm thinking to not truncate history list 
until saved, both GNU and builtin.)
