* tests/async.test: Added several tests that demonstrate Tcl

        * tests/basic.test:     Bug 489537, Tcl's longstanding failure to
        * tests/dict.test:      properly quote any leading '#' character
        * tests/dstring.test:   when generating the string rep of a list
        * tests/list.test:      so that the comment-power of that character
        * tests/parse.test:     is hidden from any [eval], in order to
        * tests/util.test:      satisfy the documentation that [list] does
        [eval]-safe quoting.
