This test saves standard output and error, but doesn't look at them.

Don't run git commands upstream of a pipe, because the pipe hides
their exit code. This applies to several other tests below as well.
Wouldn't a 'sed' one-liner suffice, so we won't have yet another perl
dependency?

Please make sure that this "not a commit" message goes to the file
descriptor it is supposed to, i.e., assuming it's part of an error
message:
test_must_fail git rev-list .... 2>err &&
test_i18ngrep "..." err
This applies to several other tests below and in other patches as
well.
