According to Larry Hall (Cygwin) on 11/5/2009 9:13 PM:
> What "empty line between the getfacls stanzas"?

The blank line that is output after one getfacl process ends.  Try
'getfacl . .; getfacl .' vs. 'getfacl .; getfacl . .' to see it.

The number of command line arguments pieced together without exceeding
exec() limits is dependent on the sum of the command line length and the
size of the current environment; but since the 'find -exec {} +' and 'find
- -print0 | xargs -0' approaches see a slightly different environment
variables (in particular, $_ will be a different length between the two
invocations), the wraparound point for creating new processes differs.

But if you WANT to guarantee a newline between processes, just ask for it.
 Here's one way:

find -print0 | xargs -0 sh -c 'getfacl "$@"; echo' sh
