[PATCH v2 0/3] t7800: fix quoting of looped test bodies

Hi,

this is the second version of my patch series that aims to address some issues with looping around `test_expect_success` in t7800.

Changes compared to v1:

    - Fixed indentation of a paragraph in "t/README".

    - Added a clarification why one wants to use single quotes to
      "t/README".

Thanks!

Patrick
