#2720 — bug when using pslatex

I noticed with the following strange Gnuplot behaviour which very much looks like a bug to me:

I checked this for three versions of Gnuplot:
G N U P L O T Version 5.1 patchlevel 0    last modified 2015-01-20 
G N U P L O T Version 4.6 patchlevel 0    last modified 2012-03-04 
G N U P L O T Version 4.7 patchlevel 0    


Start Gnuplot en enter the following commands:
set terminal pslatex size 25cm,17cm
set output 'test.tex'
plot x**2

When you have a look at the resulting test.tex file, the following three lines at the end of the file are missing:

\end{picture}%
\endgroup
\endinput

When running "set output 'test.tex'" and "plot x**2" a second time, a file test.tex without this error is produced.

I also noticed that when I put the three commands in a batch-file test.gp and run 
them as gnuplot <test.gp the file produced is also error free.

kind regards,
Hugo Coolens

p.s. I remember having noticed this behaviour years ago when using wxmaxima
which uses Gnuplot for graphics

You have forgotten to close the output file via "set output". Only then
the three missing lines are added. I´m not exactly sure why this is done
the way it is.

set term pslatex
set out "test1.tex"
plot x
set out

You´re welcome.

It is funny though, why gp actually writes/closes the file, and then
reopens it to append those three lines.

What's also strange is that for other file-type like png or postscript, the extra statement "set output" is not necessary. That's the reason why I didn't do it until now for pslatex neither

It differs. pdfcairo for example only writes to disk upon closing the
file. Before it is just size zero.
