You are right. They went upstream 2009. I will remove these patches for 
the next review round.

I read that disable-nls removes all gettext dependancy. To avoid some 
trouble I disabled it for the first version.
Let me know if you like to have the nls option in the introductory 
version. I guess activating it if BR2_LOCALE and BR2_GETTEXT is set is 
the right way.
I think nls is not that important in embedded environments. It just used 
to function.  That's way I look at this with prio 2.

Acked.

I don't think so. Maybe someone likes to compare the busybox vs. the 
"mainstream" version. So you should be able to install both.
The busybox binary still can be launched with the applet parameter to be 
behave like mount. That's why I added the comment. In fact it is only 
visibible when BUSYBOX_SHOW_OTHERS is true. So the user should know, 
that he gains some redundancy if busybox remains enabled.
The same for LIBUUID. But this is a library, so maybe it's better here 
to forbid installing both. Let me know.

See comment above. I read somewhere that disable nls removes need for 
gettext.
I will  cross check this.

Acked - if you accept indents in if-blocks ;-)

Honestly, I dont't know. I took the original dependancy introduced by 
Daniel Mierswa:
http://article.gmane.org/gmane.comp.lib.uclibc.buildroot/16587/match=util+linux+ng
I'll will change (and test) to just activate ncurses --with-ncurses when 
BR_NCURSES is available. Which sounds more logical now...

No problem. I needed this for xfsprogs. Feel free to review this patch, 
too ;-)
