Subject: [PATCH] minimal/do: fix failure with paths containing spaces.

We grew a test for these at some point, but minimal/do didn't actually
pass it.

sh syntax oddity: if you say
    x=$1 y=$2
then it works fine when $1 and $2 contain spaces.  But if you say
    export x=$1 y=$2
(or "local" instead of "export") then $1 and $2 will be split on IFS,
and it won't do what you think.  I guess this is because 'export' and
'local' are like commands, and command arguments are split if not
quoted.
