emacs -Q
C-x C-f foo-<-4-n.el
Type some text in that file buffer.
C-x C-s ; try to save it.
Saving file d:/usr/drew/drews-lisp-20/foo-<-4-n.el...
basic-save-buffer-2: Opening output file: invalid argument, d:/.../foo-<-4-n.el
Apparently it doesn't like `<' in a file name? If so, and if that is
"normal", then the user should get a much better error message than
this.
(Same problem in the latest Emacs 25 build I have.)
In GNU Emacs 24.5.1 (i686-pc-mingw32)
of 2015-04-11 on LEG570
Windowing system distributor `Microsoft Corp.', version 6.1.7601
Configured using:
`configure --prefix=/c/usr --host=i686-pc-mingw32'

Yes, Windows doesn't allow that.

That's the error that comes from the filesystem, Emacs doesn't know
any better.

Right, cf https://support.microsoft.com/en-us/kb/177506
Is it worth blocking this sort of file name in read-file-name, or
should we just mark this wontfix?

No, I don't think so, because MS-Windows includes a pluggable
filesystem design, whereby any 3rd party filesystem device driver
could be added, which supports these characters in file names. We
simply cannot know up front which filenames are invalid.

I think so, yes.
Thanks.
