* generic/tclBasic.c (TclAppendObjToErrorInfo): New internal routine

        that appends a Tcl_Obj to the errorInfo, saving the caller the trouble
        of extracting the string rep.

        * generic/tclStringObj.c (TclAppendLimitedToObj):       New internal
        routine that supports truncated appends with optional ellipsis marking.
        This single routine supports UTF-8-safe truncated appends needed in
        several places throughout the Tcl source code, mostly for error and
        stack messages.  Clean fix for [Bug 760872].

        * generic/tclInt.h:     Declarations for new internal routines.

        * generic/tclCmdMZ.c:   Updated callers to use the new routines.
        * generic/tclCompExpr.c:
        * generic/tclCompile.c:
        * generic/tclExecute.c:
        * generic/tclIOUtil.c:
        * generic/tclNamesp.c:
        * generic/tclObj.c:
        * generic/tclParseExpr.c:
        * generic/tclProc.c:
        * generic/tclStringObj.c:
        * mac/tclMacResource.c:

        * library/init.tcl:     Updated ::errorInfo cleanup in [unknown] to
        reflect slight modifications to Tcl_LogCommandInfo().  Corrects
        failing init-4.* tests.
