Summary: arguments to TclCreatePipeline cannot start with '|'

Initial Comment:
Any parameter to TclCreatePipeline which begins with a pipe symbol triggers the 'command needed' case, even if it's not just a | or |&.  This makes it impossible to pass any parameter to a child process which begins with a pipe symbol.

The problem occurs on 8.4.13 but not on 8.4.7.  I haven't checked other versions.

Example:

(Tcl 8.4.7)
% exec echo |foo
|foo

(Tcl 8.4.13)
% exec echo |foo
illegal use of | or |& in command
