Gentlemen, as you know when you do M-x man and get the prompt
   Manual entry (default blabla):
there is no TAB completion.

Well as many of the man pages are the same names as shell commands, why
not just use the same completion as shell-command and
shell-command-on-region use?

It's better than nothing, and one can still enter other names too.

Help, as of debian-snapshot 1:20100118-1 I am still getting
      completion--some: Searching for program: no such file or directory, LC_CTYPE=C man
when I hit M-x man bla<TAB>
just because I have (setq manual-program "LC_CTYPE=C man") in
http://jidanni.org/comp/configuration/.emacs .

How about making this shell script "man.sh" somewher in your PATH,

#!/bin/sh
LC_CTYPE=C man $@

and set manual-program to "man.sh"?

I've just installed the patch below which should silence those errors
(tho the error will still be there and will prevent completion from
working).

Well OK but maybe the bug should not be closed completely then.
