[Gimp-docs] work in progress

[Vitaly Lomov]

the work in progress wiki page clearly stated that the render filter
folder was pegged by 'ru' in the 'doing' status and 'it' in the
'done'. Imagine my surprise (I contribute the 'ru' part) when 5 files
in the render folder were updated by 'it', making me go through all
those files and manually fix the conflicts. WTF?
Does work in progress even matter? If it does, the commiters must
respect wip and not commit the files if the corresponding translation
team did not peg the area being committed.
my 2 cents.
