I'd prefer:
2 tracepoint keep y 0x080485b1 in main at gdb.trace/change-loc.c:29
installed on target
3 tracepoint keep y 0x080485b1 in main at gdb.trace/change-loc.c:29
not installed on target
As the other similar cases of more breakpoint info more textual as well:
4 breakpoint keep y 0x0804c8a5 in main at ../../src/gdb/gdb.c:29
breakpoint already hit 1 time
This should be documented in the manual and NEWS, both the CLI changes, and
the MI change (this patch adds the "installed" field to various MI things).

Not sure about the pending case. Can you show how does that look like?
Why not just display nothing in that case? How does the MI output look
like in the pending case?
