Phil, what's your opinion about this?  gnus-mock.el wants to edit a file
it has opened with find-file-noselect, which is a common thing to do.
But it fails for me because I have enabled global-so-long-mode in my
init file and it makes the buffer read-only.  This is quite surprising
because the buffer is only used internally by gnus-mock.  Could so-long
be a bit smarter here?

TIA,

Michael.
