src/emacs -Q etc/NEWS
C-x C-q ; buttons appear
C-x C-q ; buttons donʼt disappear

(personally I donʼt mind the buttons, but the intent of faf1f037987c
was to make them disappear).

I came up with the following, but I can never remember all the details
of text property removal (maybe we need a `button-debuttonize-region'?)
