Here is a series I just cooked up so that we can remove the whole Perl
script and replace it by adding --check to "diff-index" used there. 

The first three are code clean-ups and the last two implements necessary
new features to "diff --check".  The whole series somewhat depend on the
fix to 'maint' not to lose the exit status I sent earlier.

[PATCH 1/5] diff --check: explain why we do not care whether old side is binary
[PATCH 2/5] check_and_emit_line(): rename and refactor
[PATCH 3/5] checkdiff: pass diff_options to the callback
[PATCH 4/5] Teach "diff --check" about a new blank lines at end
[PATCH 5/5] diff --check: detect leftover conflict markers
