Double space after period everywhere please.

+  ui_out_field_int (uiout, "buffer-free",  (int) ts->buffer_free);

When these optional fields aren't reported by the target, this
will print -1.  I don't see that mentioned in the manual.  Is
this intended?  I would have expected optional fields to just
not be present, as is common in MI.  trace_status_command does
that too.

Hmmm, I don't see any of the qTStatus optional fields described
anywhere in manual.  Stan?  Am I just looking at the wrong
place?
