* doc/ParseCmd.3: Implementation of TIP 157. Adds recognition

        * doc/Tcl.n:            of the new leading {expand} syntax on words.
        * generic/tcl.h:        Parses such words as the new Tcl_Token type
        * generic/tclBasic.c:   TCL_TOKEN_EXPAND_WORD.  Updated Tcl_EvalEx
        * generic/tclCompile.c: and the bytecode compiler/execution engine
        * generic/tclCompile.h: to recognize the new token type.  New opcodes
        * generic/tclExecute.c: INST_LIST_VERIFY and INST_INVOKE_EXP and a new
        * generic/tclParse.c:   operand type OPERAND_ULIST1 are defined.  Docs
        * generic/tclTest.c:    and tests are included.
        * tests/basic.test:
        * tests/compile.test:
        * tests/parse.test:

        * library/auto.tcl:     Replaced several [eval]s used to perform
        * library/package.tcl:  argument expansion with the new syntax.
        * library/safe.tcl:     In the test files lindex.test and lset.test,
        * tests/cmdInfo.test:   replaced use of [eval] to force direct
        * tests/encoding.test:  string evaluation with use of [testevalex]
        * tests/execute.test:   which more directly and robustly serves the
        * tests/fCmd.test:      same purpose.
