Steps to reproduce:

1. Create a new named search query, named e.g. "foo".
2. Visit the "Your Queries" Editing page.
3. "foo" has a menu "Private to you?" set at "yes".
4. Change the menu to "no"
5. Click "Save Selection"

Actual behavior:

Menu changes to static text "[not yours to edit]", I
can no longer change the query, and others can use the
query.

Expected behavior:

Menu changes to "no", and other people can now use the
query. But, I can still edit it, and I can change the
menu back to "yes" if I want.

Or, less desirable IMO but (barely) acceptable:

I'm asked, "this means that you will no longer be able
to edit this query. Is this OK? yes/no" and can abort
the choice.

This is on 1.1.1.

Thanks for some fabulous software,
