Ouch, I think git-formatted patches are not intended to be edited
manually :-)

Hm, does it work for you?  I looked at "mew-key.el" but the code wasn't
patched, probably something with the regexp.  Anyway it is better to
patch 'mew-icon-directory' variable instead.

Also I see that by default it puts image files into
"share/emacs/site-lisp/mew/etc".  I don't think this is a good place, I
would rather move them to "share/mew" as most packages do with various
additional files.

Also it is good to generate "mew-autoloads.el" file, so that "M-x mew"
command will be available for users by default.  I'm attaching a
modified patch to address what I mentioned.  Could you test it to make
sure that mew works as expected with it?
