• more unsigned → unsigned int

Browse Source 
• more int → bool
• more regression tests: check if the utf8-hack flag is really disabled
  at non-interactive startup, enabled at interactive startup, if the
  current locale is a UTF-8 one
• make the mksh-local multibyte handling functions globally accessible,
  change their names, syntax and semantics a little (XXX more work needed)
• optimise
• utf_wctomb: src → dst, as we’re writing to that char array (pasto?)
• edit.c:x_e_getmbc(): if the second byte of a 2- or 3-byte multibyte
  sequence is invalid utf-8, ungetc it (not possible for the 3rd byte yet)
• edit.c:x_zotc3(): easier (and faster) handling of UTF-8
• implement, document and test for base-1 numbers: they just get the
  ASCII (8-bit) or Unicode (UTF-8) value of the octet(s) after the ‘1#’,
  or do the same as print \x## or \u#### (depending on the utf8-hack flag),
  plus support the PUA assignment of EF80‥EFFF for the MirBSD encoding “hack”
  (print doesn’t, as it has \x## and \u#### to distinguish, but we cannot use
  base-0 numbers which I had planned to use for raw octets first, as they are
  used internally): http://thread.gmane.org/gmane.os.miros.general/7938
• as an application example, add a hexdumper to the regression tests ☺
