How was a cherry-pick conflict resolved ?

When a git cherry-pick fails because of a conflict, it can be resolved and committed. The reviewer is reminded that a conflict had to be resolved by the Conflicts section at the end of the message body:

commit 7b8e5c99a4a40ae788ad29e36b0d714f529b12eb
Author: John Spray 
Date:   Tue May 20 16:25:19 2014 +0100
...
    Signed-off-by: John Spray 
    (cherry picked from commit 1d9e4ac2e2bedfd40ee2d91a4a6098150af9b5df)
    Conflicts:
    	src/crush/CrushWrapper.h

The difference between the original commit and the cherry-picked commit including the conflict resolution can be displayed with:

commit=7b8e5c99a4a40ae788ad29e36b0d714f529b12eb
picked_from=$(git show --no-patch --pretty=%b $commit  |
  perl -ne 'print if(s/.*cherry picked from commit (\w+).*/$1/)')
diff -u --ignore-matching-lines '^[^+-]' \
   < (git show $picked_from) <(git show $commit)
