Alphabetical, please.  Applies elsewhere in the Makefile patch too.

Missing blank line after the date line, and typo: "texinfo", not
"textinfo".

This is not an accurate description -- it may or may not be related to a
change in the inferior.

E.g., if the user did "set auto-solib-add off", then no objfile will be
made when a shared library is loaded.

Or, if the user does "add-symbol-file", then a new objfile will be made
even though nothing has changed in the inferior.

Maybe this isn't the event you actually wanted?  I mean -- it is fine to
have this, and I'd like it if you followed through :-), but it may not
do what you are expecting.

I think it is better to just return early if objfile==NULL.
Or, emit a different event in this case.

Missing newline.

I think clean_restart is preferred here.
But maybe skip_python_tests has to be inserted in the middle of the
sequence?

Kevin> +gdb_test "run" ".*event type: new_objfile.*
Kevin> +.*new objfile name.*"

This style of test is hard to read.  I'd prefer a \n in there.
