#2497 terminal setting in gnuplot.ini or .gnuplot is not displayed propely

[Tatsuro MATSUOKA]

This may not be a bug but is better to be considered.
In windows version gnuplot (5.2, 5.4 and 5.5),
I wrote in %APPDATA%gnuplot.ini

set terminal wxt font 'Arial'

and start gnuplot

In the gnuplot opening windows :

Terminal type is now 'qt' (<==qt???)
gnuplot>

gnuplot> show terminal
terminal type is wxt 0 enhanced font "Arial"

Description of gnuplot.ini for terminal setting is definite set but the timing was not proper.

I also have confirmed the similar behavior for ~/.gnuplot in the cygwin.

    * src/gadgets.c src/plot.c src/term.c (load_linetype):
    A 2017-04-10 patch re-ordered initialization to (1) error handling,
    (2) session state, (3) default terminal.  This had the effect that a
    command in ~/.gnuplot that queried terminal state could segfault
    because the terminal had not yet been initialized.  Now we reorder again
    to (1) error handling (2) terminal (3) session state from ~/.gnuplot.
    For safety also add sanity checks in load_linetype() so that
    term == NULL does not segfault.

Thank you for the pointer (Commit: [fb1214]).

Now we reorder again to (1) error handling (2) terminal 
(3) session state from ~/.gnuplot.

However, we can also set default terminal in ~/.gnuplot (%APPDATA%\gnuplot.ini in windows) and setting default terminal in gnuplot.ini are described in ReadmeWindows.txt in windows distribution.

 Alternatively, you can add
    set term windows / wxt / qt
to your gnuplot.ini, see `help startup`.
