misc: introduce print_usage_help_options()

Consolidate --help and --version descriptions. We are
now able to align them to the other options.

We changed include/c.h. The rest of this patch was
generated by sed, plus manually setting the right
alignment numbers. We do not change anything but
white spaces in the --help output.
