Hmm, there indeed are quite a many "At this point, the variable's
value must be this" in the test scripts.  With things like this:

    t/     test "$SHA" = "$(git rev-list HEAD)"

we can go to the trash directory upon seeing a failure to run the
command used on the RHS, but the value in $SHA is cumbersome to find
out (either running it under sh -x or insert an extra echo before
it), so such a helper function may be useful.

Do you really need a general comparison ("does A sort before B") or
just equality?  If the latter, test_string_equal (or even
string_equal) might be a better name for it.

By the way, test_cmp() is a replacement for the "cmp" command and
that is why it does not have "file" in its name.
