Most libxo-enabled utilities link to xo_parse_args.3. But that man page
doesn't actually describe how to format command-line arguments. Rather,
xo_options.7 does. I suspect that these utilities link to the former
because the latter man page did not exist until libxo-0.7.2
(8a6eceff3ce). And newer utilities have probably been copy/pasting the
same text from older ones. But the superior man page does exist now,
so we should link to it instead.

netstat -i: compute most field widths dynamically

The network and address fields were sometimes truncated for netstat -i
without -W, and often much too wide for netstat -i with the -W option.
Fields such as normal packet counts often overflowed. As a result,
columns didn't line up, and large white spaces made it harder to
follow a line across the display. Change the code to compute the
required field sizes for network, address, and various packet counts.
Hoist the code to format network and address into a subroutine that
can be called twice, once to measure the required field widths,
and once to emit the values. Use separate field widths for input
and output packets, byte counts, and error and drop counters.
These are left at defaults (the preceding values) with the -h
option, in which case the fields have a limited total width.
An extra space is included between the Network and Address, which
otherwise seemed too close.

Change the mention of -W with -i in the man page to say that most
field widths are computed dynamically in this case.

netstat -i: do not truncate interface names

The field for interface names for netstat -i was 5 characters by
default, which is no longer sufficient with names like "vlan1234"
and "vtnet0". netstat -iW computed the necessary field width, but
also enlarged the address field by a lot (especially with IPv6 enabled).
Make netstat -i compute the field width for interface names with or
without -W. Note that the existing default output does not fit in
80 columns in any case. Update the man page accordingly, documenting
the remaining effect of -W with -i. Also add -W to the list of
General Options, as there are numerous pointers to this.

With M_EXTPG mbufs these two counters already do not represent the
