* lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
Extracted from AS_SHELL_SANITIZE.
(_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
macros.
(AS_SHELL_SANITIZE): Move reinvocation code from
_AS_LINENO_WORKS, use it to find out if shell
functions work.
(_AS_LINENO_WORKS): Don't find another shell if $LINENO
does not work.
(AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
(AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN
was called.
* lib/autotest/general.m4: Use AS_INIT_WITH_SHELL_FN.
* bin/autoconf.in: Regenerate.
* tests/wrapper.in: Regenerate.
* tests/tools.at: Test the syntax of tests/autoconf
and tests/testsuite.
