[Ben Walton]

Avoid a GNU-ism in the cp options used by t5400-send-pack.  Change -a
to -pR.

Thanks, but is "-p" essential for this test to pass, or can we get
away with just "-R"?

Besides, when you spot a potential problem, please ask "git grep"
to catch them all.

    $ git grep "cp -a" t/
    t/t5400-send-pack.sh:   cp -a parent child &&
    t/t5550-http-fetch.sh:  cp -a .git"$HTTPD_DOCUMENT_ROOT_PATH/repo.git" &&

In other words, how about doing this instead?

Subject: tests: "cp -a" is a GNUism

These tests just wants a bit-for-bit identical copy; they do not
need -H (there is no symbolic link involved) nor -p (there is no
funny permission or ownership issues involved).  Just use "cp -R"
instead.

This works.  I was responding to a failing test so I didn't look for
other instances.  Clearly I should have...I must not be exercising
those other tests.

I actually was planning to pass the blame to you so I'll re-queue it
under your "Author:" name, with S-o-b.

Thanks.

There's 2 more places in Documentation/git-tutorial.txt. There it looks like 
we'd want to use 'cp -pR' instead
