tests: avoid a "grep -E" portability issue As stated in the Autoconf manual, the empty alternative is not portable with "grep -E". For example, while with GNU grep we have: $ echo b | grep -E '(|a)b'; echo status = $? b status = 0 with Solaris 10 /usr/xpg4/bin/grep we have: $ echo b | grep -E '(|a)b'; echo status = $? 1 status = 1 * t/silent-texi.sh: That was causing a spurious failure here. Fix it by simply using '?' instead (as suggested by the Autoconf manual). Signed-off-by: Stefano Lattarini <stefano.lattarini@gmail.com>
