Not a surprise.   Writing English isn't what I do well (but that is not to
mean that writing in some other natural language would be easier, of those
English is the only rational choice, though I occasionally demean myself
and write American instead...)

In a more natural form (the actual code looks nothing like this)...

	/* we are processing "set -x" */
	if (xflag == 1)
		return;
	xflag = 1;
	x_trace_file = stderr;

So...

Yes.
