A file which I've been opening in emacs and editing for a few years in
emacs suddenly with emacs version 22.1.1 became read-only. I open it,
can navigate around in it (though the cursor/mark isn't visible), but
when I try to edit it, I'm not allowed. I get a message in the
minibuffer saying, "Text is read-only". The beginning of the modeline
is "-u: --". I can open this same file in vi and edit it (as the same
user) without any problem at all. I don't have this problem with any
other file I edit in emacs, just this one. The OS is linux, kernel
version 2.6.18.384, and the permissions for this file are 664 and I am
the owner of the file. If I change (i.e., mv) the name of the file to
something else, emacs behaves normally and lets me edit the file just
like any other file. So I'm pretty sure that the problem is that emacs
has a problem with the file name and thinks I shouldn't be allowed to
edit it. How do I turn this behavior off?
