[PATCH 0/3] Falling back "diff -C -C" to "diff -C" more gracefully

In a project with many paths, "diff -C -C" may have too many rename source candidates (as it tries to use all existing paths) but the rename source candidates "diff -C" would use may still fit under the rename detection limit. Currently, we punt and disable the inexact rename detection altogether even in such a case.

This weatherballoon series illustrates how diffcore-rename can be tweaked to allow "-C -C" to fall back to "-C". Somebody should write a test, but not today ;-).

Junio C Hamano (3):
  diffcore-rename: refactor "too many candidates" logic
  diffcore-rename: record filepair for rename src
  diffcore-rename: fall back to -C when -C -C busts the rename limit
