The file didn't lose its ACL. What happens is that
a copy was created, and then renamed over the original.
At one point chmod is applied to the copy, so that it
has the right permissions. That's what removes the
default ACL.
This does appear to be a bug. One possible fix
would be for 'patch' to not do the chmod unless it really
needs to, which typically it doesn't.
This bug report really belongs in bug-patch, by the way,
so I'll CC: this followup here. The original thread is at
<http://lists.gnu.org/archive/html/bug-diffutils/2010-10/msg00015.html>.
