Currently, in the case where we are using test_cmp_rev() to report
not-equals, we write `! test_cmp_rev`. However, since test_cmp_rev()
contains
r1=$(git rev-parse --verify "$1") &&
r2=$(git rev-parse --verify "$2") &&
In the case where `git rev-parse` segfaults and dies unexpectedly, the
failure will be ignored.
Rewrite test_cmp_rev() to optionally accept "!" as the first argument to
do a not-equals comparison. Rewrite `! test_cmp_rev` to `test_cmp_rev !`
in all tests to take advantage of this new functionality.
