Even better, store the result for each window and execute it afterwards:

:let delete={}
:windo if &diff |:let delete[bufnr('')]=
join(map(filter(range(1,line('$')), '!diff_hlID(v:val, 0)'),
'''\%''.v:val."l"'), '\|')|endif
:windo if &diff | exe ":g/". delete[bufnr('')]."/d"|endif
:unlet delete

(each line starting with ':' is a single line, no linewraps)

Christian
