Consider this TCC v23.00.24 x64 session: (Discussion follows.)
The problem is that the echox internal command is interpreting everything in the command group except for the first echox, plus it is seeing command separators that were never injected except by TCC as part of its command grouping. This behavior violates the separation of functions that we programmers rely upon. I expect that if I invoke echox 3 times, then what is emitted to its output (however it is redirected or not) will be literally what followed on the 3 command tails, each followed by a newline.
