[PATCH] Fix bug in test missing6.test

[Stefano Lattarini]

Hello automakers.

The tests missing6.test in its current form produces broken configure and
config.status scripts; more precisely, it's the sed script for $LINENO
subtitution that is broken, since the sed command `b' got substituted with
the string `oops'.

(Just for the record, I found this bug while running the automake
testsuite with CONFIG_SHELL=dash).

The attached patch fixes the problem.  I checked its correctness by
temporarly reverting the change that fixed the bug tested by missing6.test
(git commit `680877cce6a85e0a55a7659048c0431109f964b7'), and verifying
that in such case `missing6.test' fails as expected.

OK for maint?

Regards,
  Stefano

Subject: [PATCH] Fix bug in test missing6.test.

* tests/missing6.test: Fix the hack used to edit `configure.in',
to avoid producing a configure script that breaks with shells
that do not support $LINENO.  Also throw in a couple of cosmetic
changes.
