Yeah, either that, or "insert separator only before adding to
something else" pattern, i.e.
for (i = 0; i < argc; i++) {
if (i)
addch(&msg, ' ');
addstr(&msg, argv[i]);
}
Both are easier to read than "always append SP and trim at the end".
Besides, trimming at the end makes readers wonder if there are cases
where argv[argc-1] ends with whitespaces and the code on purpose
removes them.
