[PATCH v2 0/9] mailmap fixes

This is a re-roll of jc/mailmap-case-insensitivity [1] in 'pu', which fixes an off-by-one parsing bug and a case-losing bug in mailmap.

Changes since v1:

* Replace v1 [4/4] with new [1/9] and [3/9] which explicitly demonstrate
  each bug being fixed.

* Fix several crashes and issues in mailmap debug code (new patches
  [5/9] through [8/9].
