* Version 6.0-cvs.
+ * src/copy.c: Improve performance a bit by optimizing away
+ unnecessary system calls and going to a block size of at least
+ 8192 (on normal hosts, anyway). This improved performance 5% on my
+ Debian stable host (2.4.27 kernel, x86, copying from root
+ ext3 file system to itself).
+ Include "buffer-lcm.h".
+ (copy_reg): Omit last argument. All callers changed.
+ Use xmalloc to allocate rather than trusting alloca
+ (which is unwise with large block sizes).
+ Declare locals more locally, if possible.
+ Use uintptr_t words instead of int words, for a bit more speed
+ when looking for null blocks on 64-bit hosts.
+ Optimize away reads of zero bytes on regular files.
+ In the typical case, insist on 8 KiB buffers, at least.
+ Avoid unnecessary extra call to fstat when checking for sparse files.
+ Avoid now-unnecessary cast to off_t, and "0L".
+ Avoid unnecessary test of *new_dst when checking for same owner
+ and group.
