I hope I don't bother, too much.

There is some problem I see when building Emacs with the patch:

It builds fine, but when I test it, it seems that I need to re-eval
after Emacs started wdired.el in order to get it to work properly. What
happeneds it that Emacs seems to run self-insert command upon entering
wdired mode anyway, despite being build with patched wdired. 

However when I eval my working file "lazy-wdired.el" it works fine. The
code is identical as one in the patch.

I also noticed when I unload-feature lazy-wdired, so I unload all those
wdired definitions, and if I eval patched wdired.el from lisp directory which I
built Emacs with, everything also works correctly too.

I am little bit confused, why do I need to re-evaluate wdired.el in a
freshly patched and recompiled Emacs to get this to work?
