Sorry, I do not get what you are hinting at.  The fact that you
passed all the tests suggests that we have a gap in the test
coverage for these two, so you are inviting more tests from
others?

As long as you have this, I do not think you can avoid breaking
existing repositories that have:

        [core]
                autocrlf
		filemode =

and expect git to say "Ah, core.autocrlf is set to true, and
filemode is not trustable, so I need to do a MS-DOG".

	$ git config --bool core.autocrlf
        true
        $ git config --bool core.filemode
        false

Your "builtin-config.c" patch looks better than before (which
would segfault), but I think

	$ git config --bool --list

could pay attention to the "type" thing set earlier, just like
show_config() does.
