As far as I can see, this is a bug in 'patch', as 'patch' currently violates POSIX in this respect. <http://www.opengroup.org/onlinepubs/007904975/utilities/xcu_chap01.html#tag_01_07_01_04> says that when a standard utility writes an existing regular file, it should not unlink and then create it; it should simply open it for writing. > It needn't be the default, but it certainly should be an option, Yes, it would be reasonable to add it as an option.
