Update doc/src/dump.rst

I have noticed that the documentation of the dump command still reports the following convention:

.. parsed-literal::

   ITEM: BOX BOUNDS xx yy zz                                                                                                                                                          
   xlo xhi
   ylo yhi
   zlo zhi

and

.. parsed-literal::

   ITEM: BOX BOUNDS xy xz yz xx yy zz
   xlo_bound xhi_bound xy
   ylo_bound yhi_bound xz
   zlo_bound zhi_bound yz

…while the string xx yy zz was removed from the source code of the dump command.
Is it better to report these minor changes here or open an issue on GitHub?

This is actually correct. Please read the text below. The xx yy zz characters stand for the boundary condition for lower/upper box boundaries in x, y, and z.

Either works. In this specific case mentioning this here is easier and less disruptive.
I would just use the “LAMMPS Development” category.

Oh, now I see. I shouldn’t ramble late at night! :rofl:
