ido-show-dot-for-dired

[Christoph Scholtes <cschol2112@googlemail.com>]

Is there a reason why ido-show-dot-for-dired only has an effect in file 
name lists and not dir name lists?

I.e. (setq ido-show-dot-for-dired nil) will not show the dot in file 
name lists, but it will in dir name lists always, e.g. with C-x d. I 
think it's annoying to have the dot in the dir list and have to do C-s 
when I could just hit Enter to get to the only other subdirectory.

So, I am proposing to extend ido-show-dot-for-dired to include the 
directory lists. Setting ido-show-dot-for-dired to nil would disable the 
. in file and directory lists or enable it in both with non-nil.

Unless somebody comes up with a reason why you would want it in one and 
not the other, this patch would accomplish it:
