  tests: simpler workaround for shells losing the exit status in exit trap
  
  Now that we can assume our tests are run by a decent POSIX shell, we
  can simplify our workaround aimed at having the exit status propagated
  correctly to the code in the exit trap.  Unfortunately, we cannot
  dispense with such a workaround altogether, because it's still required
  by some shells we need to support (at least Solaris 10 /bin/ksh and
  /usr/xpg4/bin/sh).
  
  For more information about the need of that workaround, see the entry
  about 'trap' in the section "Limitations of Shell Builtins" in the
  Autoconf manual:
  <http://www.gnu.org/software/autoconf/manual/autoconf.html#trap>
  
  The new workaround has been tested successfully with the following
  shells:
  
    - Bash 4.1
    - Bash 3.2
    - Bash 3.0
    - Bash 2.05b
    - dash 0.5.5.1
    - dash 0.5.2
    - AT&T Ksh 93u (from official Debian package)
    - MirBSD Korn Shell 40.2 (from official Debian package)
    - Solaris 9, 10 and 11 /bin/ksh
    - Solaris 9, 10 and 11 /usr/xpg4/bin/sh
    - NetBSD 5.1 /bin/sh
    - NetBSD 5.1 /bin/ksh
  
  * t/ax/test-init.sh (Exit): Rename ...
  (_am_exit): ... like this.
  (exit): New alias for '_am_exit'.  We cannot simply redefine 'exit'
  as a shell function, because some shells (dash 0.5.5.1, Solaris 10
  /bin/ksh and /usr/xpg4/bin/sh) do not allow it.
  (_am_exit, trap): Add extra escaping for 'exit' calls, to ensure we
  really invoke the 'exit' builtin and not our alias with the same
  name.
  * configure.ac: Check that the shell selected to run our testsuite
  supports aliases named like shell builtins.
  * t/REAMDE: Adjust.
  * All tests: Adjust, by simply using 'exit' instead of 'Exit'.
  * t/self-check-explicit-skips.sh: Adjust: the first usage of 'exit'
  after it has been redefined as an alias must be on a new line w.r.t.
  that where the alias is defined, in order for the redefinition to be
  honored.
  * syntax-checks.mk (sc_tests_Exit_not_exit): Delete.
  (sc_tests_exit_not_Exit): New.
  (syntax_check_rules): Adjust.
  (sc_tests_automake_fails): Simplify the recipe a little.
  * Several tests: Remove now useless spurious quoting once required
  to placate the 'sc_tests_Exit_not_exit' maintainer check.
  * gen-testsuite-part: Likewise.  Also, avoid uses of 'Exit' in the
  generated scripts.
