From: Bruno Haible Date: Fri, 2 Sep 2011 12:13:59 +0000 (+0200) Subject: tests: init.sh: work also with any non-GNU diff that supports -u X-Git-Tag: v0.1~1967 X-Git-Url: https://gitweb.git.savannah.gnu.org/gitweb/?a=commitdiff_plain;h=641823b46475021617cb75ddde164bec4af1c99f;p=gnulib.git tests: init.sh: work also with any non-GNU diff that supports -u * tests/init.sh: Relax check for diff -u support. Rather than checking for GNU diff via --version, simply check for support for -u itself.
