[PATCH v2 0/2] test-lib-functions: fix test_subcommand_inexact

Junio discovered in [1] that test_subcommand_inexact is more flexible than initially intended.

[1] https://lore.kernel.org/git/xmqq4k41vdwe.fsf@gitster.g/

The intention was that we do not need to specify the remaining arguments for a subcommand, but instead the current behavior is to allow the given arguments to appear as any subsequence within the command (except that the first "git" instance must be the first argument).

This changes the helper to be more rigid.

Changes in v2 =============

 * After noticing that t7700 fails with the helper change, Taylor wrote a
   modification of the test to check the post-conditions directly and avoid
   the helper. This is included as Patch 1 with some modifications to be
   easier to read.

 * Patch 2 is the v1 patch with some change to the commit message about why
   the tests pass after patch 1.

Thanks, -Stolee
