* Version 4.1.6.
+ * src/copy.c (copy_reg): Don't treat errno==ENOENT as a special case.
+ (same_file_ok): Detect a case that would have lead to the errno==ENOENT
+ condition above (and a misleading diagnostic), and return 0 so we give
+ a diagnostic about the source and destination being the same file.
+ (copy_internal): Use an explicit test for errno==EXDEV to detect
+ that rename has failed because source and destination are on
+ different devices. This reverts part of a change from 1997-12-13,
+ and is to avoid letting a race condition evoke a bogus diagnostic.
+ Note that while POSIX has encouraged the errno==EXDEV test for
+ years, it was inadequate back in 1997. I'm hoping that many
+ more systems have conforming support these days.
