parse-options: report uncorrupted multi-byte options

Because our command-line parser considers only one byte at the time
for short-options, we incorrectly report only the first byte when
multi-byte input was provided. This makes user-errors slightly
awkward to diagnose for instance under UTF-8 locale and non-English
keyboard layouts.

Report the whole argument-string when a non-ASCII short-option is
detected.

Makefile: avoid infinite loop on configure.ac change

If you are using autoconf and change the configure.ac, the
Makefile will notice that config.status is older than
configure.ac, and will attempt to rebuild and re-run the
configure script to pick up your changes. The first step in
doing so is to run "make configure". Unfortunately, this
tries to include config.mak.autogen, which depends on
config.status, which depends on configure.ac; so we must
rebuild config.status. Which leads to us running "make
configure", and so on.

It's easy to demonstrate with:

  make configure
  ./configure
  touch configure.ac
  make

We can break this cycle by not re-invoking make to build
"configure", and instead just putting its rules inline into
our config.status rebuild procedure.  We can avoid a copy by
factoring the rules into a make variable.

Documentation/submodule: Add --force to update synopsis

In commit 9db31bdf (submodule: Add --force option for git submodule
update, 2011-04-01) we added the option to the implementation's usage
synopsis but forgot to add it to the synopsis in the command
documentation.  Add the option to the synopsis in the same location it
is reported in usage and re-wrap the options to avoid long lines.
