[PATCH v5 0/2] show-index: fix uninitialized hash function

[Abhijeet Sonar <abhijeet.nkt@gmail.com>]

In this iteration, I have fixed some typos along with a stylistisc issue
that were noted in v4.

I have also added an additional patch that adds a test for --object-format
option in show-index as it was noted we don't already have any.

  show-index: fix uninitialized hash function
  t5300: add test for 'show-index --object-format'
