Subject: [PATCH] examples: beware of shell portability issues
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This completes 2d7e7438024e47650c3a0c9f5f313c6eb6acae2d.

Some shells don't grok "local var=`cmd`" very well: they need the rhs
to be quoted.

    ./examples/test: 72: local: you.,: bad variable name
    FAIL examples/variant.test (exit status: 2)

Reported by Étienne Renault.

* examples/test (run): Quote the values in 'local' assignments.
