there is write_file_gently() for that purpose, but it's used only by a
single caller that exits on failure after all, and in fact Peff's series
drops it.
So I think write_file() is fine, and it's rather a question of whether
am should use write_file_gently() instead. I don't see why, but perhaps
that's because it's Friday..
