* generic/tclBasic.c (Tcl_EvalEx): Restored recursion limit

        * generic/tclParse.c (TclSubstTokens):  testing in nested command
        * tests/basic.test (basic-46.4):        substitutions within direct
        * tests/parse.test (parse-19.*):        script evaluation (Tcl_EvalEx)
        that got lost in the parser reforms of Tcl 8.1.  Added tests for
        correct behavior.  [Bug 1115904]
