From what I can make out (largely thanks to Google Translate), the proposed translation is pretty much correct (and makes minor alterations in sentence structure).
Now I understand that such edits always carry the possibility of distorting the author's actual intentions (which counts in favor of rejecting the edit), but if it is the (seemingly) only means of making (a fairly good) question more accessible to the rest of the community, why not approve the edit (especially when it appears to be accurate)?
P.S. I neither approved nor rejected the said edit, but it looks good IMHO.
As of now, Martin and TAR already approved the edit. Accordingly, I've retracted my (unclear) close-vote on the said question and upvoted.
