On systems with /bin/sh being different than /bin/bash, make test fails due
to some bash-specific constructs. This patch makes it possible to run the
test-suite systems with on /bin/sh pointing to /bin/ksh.

These should probably be using the new test_must_fail instead of '!'
anyway.

I do not think you need a subshell for this particular test, so your
change would not be making anything worse, but I do not see a point.

It is a plain vanilla POSIX shell construct; "! ( compound_list )" is not a
bash-ism at all.

Same comments apply.

Having said that, as both of these tests are trying to make sure that the
command fails gracefully (iow, say "failure" and refuse, instead of
barfing and dumping core), they could probably use test_must_fail, like
this:

     git checkout -b delete-me master &&
     rm .git/refs/heads/delete-me &&
     test refs/heads/delete-me = "$(git symbolic-ref HEAD)" &&
-    !(git checkout --track -b track)'
+    test_must_fail git checkout --track -b track'

```
