To me it is a matter of personal preference to keep them separate. If there is, however, any technical or project-style-related reason to get them together, I'll certainly do it. >> +static void print_modified(void) >> +{ >> + int i; >> + struct add_interactive_status s; >> + const char *modified_fmt = _("%12s %12s %s"); > > We cannot really translate that...

I cannot find any call to N_() outside of Perl code.

I thought calling status_cmd() would make that more clear, but I agree -- the options already make it clear enough, I agree with all points I did not directly address. And thank you for the review :) -- Daniel.
