Of course! :-)

Just for clarity and completeness, I'll mention that this is more
about our handling of readline inside GDB than release management.
But I've had to deal with readline issues before, so I think I know
the process, which is basically:

  - Patch locally, and submit the patch to readline;

  - Keep track of the patch submission on the readline end;
    when a patch is applied, if different from the one accepted
    upstream, then undo our local patch, and apply the one from
    upstream. This ensures the one applied upstream doesn't introduce
    some issues we haven't seen during review.

Another version of the process is when the fix was already applied
upstream. In that case, no need to submit anything, since it's already
fixed. We just backport the fix from upstream into GDB's version
of readline.
