Release Status: release

        A backslash inside `...` leads to a parse error when it is the
        last character in a single quoted string.

        $ cat x.sh
        foo `bar 'a\'`
        $ sh x.sh
        x.sh: line 1: unexpected EOF while looking for matching `''
        x.sh: line 2: syntax error: unexpected end of file
