added hidden --fake-cmdline parameter for testing command-line editing

* Supports all immediate editing commands.
  Naturally it cannot emulate arbitrary key presses since there is no
  canonic ASCII-encoding of function keys.
  Key macros are not consequently also not testable.
  The --fake-cmdline parameter is instead treated very similar to
  a key macro expansion.
* Most importantly this allows adding test cases for rubout behavior
  and bugs that are quite common.
* Added regression test cases for the last two rubout bugs.
* It's not easy to pass control codes in command line arguments in
  a portable manner, so the test cases will often use { and }.
  Control codes could be used e.g. by defining variables like
  RUBOUT=`printf '\b'`
  and referencing them with ${RUBOUT}.

    This may be a viable way to run SciTECO "cross"-platform, at least
    for evaluation... on UNIX-like systems in absence of prebuilt binaries.
