​That's right, sorry.​ Fixed.

I don't understand what happened to the comment about *.JPG files on
> case-sensitive filesystems,


I took it into account. My experience is that on a case-insensitive system
(e.g. a GNU system), one finds occasional files like this, typically copied
from other systems or extracted from archives. These are not a problem for
dired-omit-mode. For visiting such files, treating auto-mode-alist and
similar case-insensitively is no problem.

It doesn't, I've fixed it in the same way as the usage of auto-mode-alist,
by testing the system type.

​See above. The only people I can see complaining are users of
case-insensitive file systems on case-sensitive systems. The correct fix
there is in any case to use the case-sensitivity of the file system, rather
than using the operating system as an indicator of that. (The same applies
to auto-mode-alist.)

Btw, if the problem is only with COPYING.LIB, maybe a better

​I don't think special cases are a good idea. There are other examples,
e.g. CVS is a pattern, which will also match "cvs", which I have in e.g.
wiki CVS repositories.

​I also added a couple of additional patches to tidy up obsolete
documentation, comments and code from dired-x.el.​
