* lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use Sed rather than

Awk.  Fix the sed prepass to work even if there are multiple
instances of $LINENO on the same line.  Do not substitute for
other variables like $LINENOT.  Do not check file dates; such a
check is unreliable on sufficiently fast machines, and removing
the check makes the code simpler and more reliable.  Check for
output and chmod failures.

* doc/autoconf.texi (Special Shell Variables): Document the above.
