Caught by make check after sending the patch (I invoked ./testsuite 
manually before sending the patch).

_AS_LINENO_PREPARE is not reinvoking the shell; the difference between 
AS_INIT and AS_INIT_WITH_SHELL_FN is that the latter exits if shell 
functions are not found.  I took this path because AS_INIT_WITH_SHELL_FN 
tried to divert AS_SHELL_SANITIZE on M4SH-INIT, so doing

$SHELL<<\_ASEOF
AS_INIT_WITH_SHELL_FN
_ASEOF

did not work.

Actually it did not -- the difference is that _AS_LINENO_PREPARE no 
longer tries to find a better shell.

Thank you very much.
