The verify_object() function in "mktag.c" is tasked with ensuring that our tag refers to a valid object. The existing test for this might fail because it was also testing that "type taggg" didn't refer to a valid object type (it should be "type tag"), or because we referred to a valid object but got the type wrong. Let's split these tests up, so we're testing all combinations of a non-existing object and in invalid/wrong "type" lines. We need to provide GIT_TEST_GETTEXT_POISON=false here because the "invalid object type" error is emitted by parse_loose_header_extended(), which has that message already marked for translation. Another option would be to use test_i18ngrep, but I prefer always running the test, not skipping it under gettext poison testing.
This is fairly unconvincing. Why do you prefer it that way? What is
so special in these tests of 'git mktags' that could possibly warrant
this special treatment WRT gettext poisoning, as opposed to the other
~1500 invocations of test_i18n{grep,cmp}?

I'm not testing this in combination with "git replace". That'll be done in a subsequent commit.
