The only changes I dont understand without explanation are those to 
AddTagsCompletionBox::setItems. What is achieved here? 
Assume you have three tags "Albert", "Alice" and "Bertha" (parent tag is 
"People"). You want to assign "Alice" to your photo. With current digikam, you 
get the following situation after each keystroke:

keystroke:items displayed
"A":"Create A in People", "Albert","Alice","Create A"  (Case A as labeled in 
"l":"Create Al in People", "Albert","Alice","Create Al" (Case A)
"i":"Create Ali in People","Alice","Create Ali" (Case A)
"c":"Create Alic in People","Alice","Create Alic" (Case A)
"e":"Alice","Create Alice" (Case C)

Please note that only after the fifth character, you can press enter to commit 
your tag. The first item is always selected, you can only press enter if your 
desired item is at position one. Now let's look at my patch, same scenario

"A":"Albert","Alice","Create A in People","Create A" (Case A)
"l":"Albert","Alice","Create Al in People","Create Al" (Case A)
"i":"Alice","Create Ali in People","Create Ali" (Case A)

After the 3rd character, you can press enter. Since I remember the chosen 
tags, "Alice" will be the first item for another photo (this logic is not in 
the setItems function, though). Assume you want to tag a second photo with 

"A":"Alice" "Albert" "Create A in People" "Create A"

Now you can already press enter after the first character, and you're done. 
With the current digikam version, you need to write the entire name.

What I have to admit: I don't know how you can actually get into case B (no 
item selected at all). I checked with debug statements, and didn't figure out 
a way to hit that codepath, with current digikam as well as with my patch 
applied. But if this codepath is hit, the code should behave correctly.

Does it become more clear to you what my modifications in setItems do?

Make tagging more accessible by keyboard

 * Pressing "T" will focus the tagedit-box.
 * The tag is applied by pressing enter. Pressing enter a second time will
   focus the mainwindow and advance to the next image.
 * The dropdown of the tagedit-box remembers already entered tags, the
   order of the dropdown items are sorted such that already entered tags 
appear first. 

I successfully use this feature on a regular basis. Also tested with current 
HEAD, works fine.
