It seems to me that `run_trailer` is used only in the `if
(trailer_args.nr) {...}` block, so it could be declared there instead
of as a global variable.

I am not sure that this `trailer`variable is really needed. It seems
to be used only as the third argument to OPT_CALLBACK(), but there are
other places in the code base where we pass NULL as the third
argument.
