Out of memory with diff.colormoved enabled

[Orgad Shaneh]

Hi,

git version 2.15.0.rc0 (from debian sid package)

There is an infinite loop when colormoved is used with --ignore-space-change:

git init
seq 20 > test
git add test
sed -i 's/9/42/' test
git -c diff.colormoved diff --ignore-space-change -- test
