Thanks for letting us know about the copyright assignment issue.
For this patch, it's sufficiently small that we can accept it
without the assignment.

There is one small change I made prior to pushing it: I added
a reference to the PR in the ChangeLog and the revision log
(as "PR python/26586" at the start of each ChangeLog entry),
so as to make sure the commit gets linked in the bugzilla PR.

@Andrew, would you agree that this patch would be safe enough
for backporting to the gdb-10-branch?

Thanks,
