[PATCH 0/5] diff --ignore-case

This teaches our "diff" machinery to optionally consider lines that are different only in upper/lower-cases to be equivalent.

Junio C Hamano (5):
  xdiff: remove XDL_PATCH_* macros
  xdiff: PATIENCE/HISTOGRAM are not independent option bits
  xdiff: introduce XDF_INEXACT_MATCH
  xdiff: introduce XDF_IGNORE_CASE
  diff: --ignore-case
