Yes, don't touch the CHANGELOG file - that gets automatically updated by WD. 
When you create the patch with git-format-patch, you need to edit that patchfile 
and insert a changelog description before sending it.

This script can make your life easier:

#!/bin/sh

CHANGELOG=git-changelog.txt
COMMENT=git-comment.txt

# Check to see if your version of git-diff supports --ignore-space-at-eol
if [ "`git-diff --ignore-space-at-eol --name-only -p HEAD | grep \"$usage: 
git-diff\"`" == "" ]
then
     IGNOREEOL=--ignore-space-at-eol
fi

function catfile()
{
     count=0
     while read line
     do
         let count++
         lines[$count]="$line"
     done < $1

     firstline=1
     lastline=$count

     while [ "${lines[$firstline]}" == "" ]
     do
         let firstline++
     done

     while [ "${lines[$lastline]}" == "" ]
     do
         let lastline--
     done

     i=$firstline
     while [ $i -le $lastline ]
     do
         echo "${lines[$i]}"
         let i++
     done
}

if [ "$1" == "" ]
then
	echo "Usage: $0 \"git-commit-comment-in-quotes\""
	exit
fi

echo "Commiting these files:"
FILES=`git-diff-index --name-only -p HEAD`

# We always update the index, because having it not updated is just confusing
git-update-index $FILES

ls -1 $FILES

# Also display a list of diffs with extra spaces
git-diff-index --check -p HEAD

echo "Ready?"
read line

git-commit -a -m "$1"

PATCHFILE=`git-format-patch -s $IGNOREEOL HEAD^ `

# If a changelog or comment file exists, then insert it

if [ -r $CHANGELOG -o -r $COMMENT ]
then
     rm -f /tmp/$PATCHFILE
     IFS=""

     while read line
     do
     	echo "$line" >> /tmp/$PATCHFILE
     	if [ "${line:0:9}" == "Subject: " ]
     	then
             if [ -r $CHANGELOG ]
             then
                 echo "" >> /tmp/$PATCHFILE
                 catfile $CHANGELOG >> /tmp/$PATCHFILE
             	echo "" >> /tmp/$PATCHFILE
             fi
     	fi
     	if [ "$line" == "---" ]
     	then
             if [ -r $COMMENT ]
             then
                 echo "" >> /tmp/$PATCHFILE
             	catfile $COMMENT >> /tmp/$PATCHFILE
             	echo "" >> /tmp/$PATCHFILE
             fi
     	fi
     done < $PATCHFILE

     mv -f /tmp/$PATCHFILE $PATCHFILE
fi

echo "Created patchfile $PATCHFILE"
