* m4sh.m4 (_AS_TEST_PREPARE): Discard output when testing `test

-x' and `test -f' to avoid confusing users with error messages.
(AS_MKDIR_P): Invert order of separators in IFS to avoid problem
with some shells adding backslash between fields and parsing the
result for escapes.
* doc/autoconf.texi (Special Shell Variables): Document IFS.
