Here's my take on your code. This will protect directory names with spaces as well as optimize the performance a bit:

#!/usr/bin/env bash
IFS="
"
START=${1:-.} # pass starting directory as arg or assume current directory
d=($(find . -type d ! -name '.*' -maxdepth 1 -print))
for ((i=0,j=1,k=${#d[@]}-1;i "${d[$j]}_changes.patch"
done
# Overview: 
# If (a b c d) dirs were found:
#   compare a to b > b_changes.patch
#   compare b to c > c_changes.patch
#   compare c to d > d_changes.patch
# * This script will protect directories with spaces in their names

Sorry.. Had to escape some characters. Here it is again.

#!/usr/bin/env bash
IFS="
"
START=${1:-.} # pass starting directory as arg or assume current directory
d=($(find . -type d ! -name '.*' -maxdepth 1 -print))
for ((i=0,j=1,k=${#d[@]}-1;i<$k;i++,j++)); do
    echo diff -ru "${d[$i]}" "${d[$j]}" > "${d[$j]}_changes.patch"
done
# Overview: 
# If (a b c d) dirs were found:
#   compare a to b > b_changes.patch
#   compare b to c > c_changes.patch
#   compare c to d > d_changes.patch
# * This script will protect directories with spaces in their names
