completion menu flicker

[Nicolas Weber]

Hi,

I sent this comment in a reply to another mail, seems it got lost. I'm 
resending it in a "thread" on its own:

When I have a completion menu that's long, but still completely fits the 
current window (say, 30 entries) and I hit hit <C-N> or <C-P> the whole 
list is redrawn (ie, it flickers). Is there a technical reason why not 
only two lines (the one that was selected before <C-N> and the one 
selected after <C-N>) are redrawn? If not, could someone give me a 
pointer what I can do to change this?

Thanks,
Nico
