since in the former case, the 2nd command will reset all the LJ and
Coulombic weights to 0.0 (the default).
One exception to this rule is the {extra} option itself. It is not
reset to its default value of 0 each time the special_bonds command is
invoked. This is because it can also be set by the
"read_data"_read_data.html and "create_box"_create_box.html commands,
so this command will not override those settings unless you explicitly
use {extra} as an option.
