An alternative approach would be to do what we do in the
print_modules() (the list of modules which can definitely
be longer than 1K chars).
We can split command line in a loop - memchr(pos, ' ') - and
pr_cont() parts of the command line. pr_cont() has overflow
control and it flushes cont buffer before it overflows, so
we should not lose anything.
