This means you'll be re-writing over this line with the following
code... (follow at [*], below)

[*] ... when you could have drawn only the needed part here:

+ wmove(stdscr, 1, len+1);
+ for (i = len + 1; i < COLS - 1; i++)
+ waddch(stdscr, ACS_HLINE);

Although this is strictly a bug fix, I would lean toward waiting for the
next merge window to open before pulling this in.

We can't really say that the kconfig frontends are critical, long-running
processes. If they leak a bit of memory, that's not too cumbersome, I
think. OTOH, I think breaking the frontends so close to the end of the
-rc cycle is a bit dangerous (heck, I would not like to be part of the
cause of a new flaming, just for this! ;-) )

So, unless Michal really wants to pull this one and push it to Linus
before he cuts v3.9 final, I'll merge this later in my -for-next branch.

Thank you!

Regards,
Yann E. MORIN.

BTW, in you are going to rebase the commit, it would be good idea to add

Indeed Yann, we can even remove one wmove() and one level of indentation in
dialog_clear().

I'm not sure who's pulling from who and where patches are going, but this
would supersede what's in yem-kconfig-for-next now.
