Thank you. And even if I use this estimable OS
  http://www.freebsd.org/cgi/man.cgi?query=wget&manpath=SuSE+Linux/i386+11.3
it provides wget-1.11.4, which
  http://ftp.gnu.org/gnu/wget/
dates from "2008-06-29 23:32", so I'm fully satisfied.

Oh. The test I showed downloaded a static file, which is permanently
stored on the server and naturally has a timestamp. When I repeat the
test using wx_commit_sha, I get a file that's created on the fly,
which doesn't have the desired name unless '--output-document' is used.
And it has a current timestamp. (I imagine a meaningful historical
timestamp could be determined by looking up the date of the commit,
but GitHub doesn't do that on the server and I'm not going to do it
myself on the client side.)

Okay, I think I'm ready to write and commit this.
