*
* NamespaceInscopeCmd -> inscopeCmd
*
* Invoked to implement the "namespace inscope" command that executes a
* script in the context of a particular namespace. This command is not
* expected to be used directly by programmers; calls to it are
* generated implicitly when programs use "namespace code" commands
* to register callback scripts. Handles the following syntax:
*
* namespace inscope name arg ?arg...?
*
* The "namespace inscope" command is much like the "namespace eval"
* command except that it has lappend semantics and the namespace must
* already exist. It treats the first argument as a list, and appends
* any arguments after the first onto the end as proper list elements.
* For example,
*
* namespace inscope ::foo a b c d
*
* is equivalent to
*
* namespace eval ::foo [concat a [list b c d]]
*
* This lappend semantics is important because many callback scripts
* are actually prefixes.
*
* Results:
* Returns if successful, raises TclException if something goes wrong.
*
* Side effects:
* Returns a result in the Tcl interpreter's result object.
