As I was tired of sending pull requests and sending the patches
separatly, I did a small ugly script. It might be useful for others, so
here it is:

#!/bin/sh

# Automate the process of generating a pull request, formatting the
# patches, and sending all of them by mail. This is useful because
# there are some projects in which sending a pull request is not
# enough, and sending the patches together with the pull request
# allows for a wider peer-review of the code.

base=$1
url=$2
email=$3

if [ ! -d .git ] ; then
    echo "Not in a git repo"
    exit 1
fi

summary=$(mktemp)

git request-pull $base $url > $summary

if [ $? -ne 0 ] ; then
    echo "git request-pull failed, aborting"
    rm -f $summary
    exit 1
fi

patches=$(mktemp -d)

git format-patch -o $patches -n --cover-letter --thread $base > /dev/null

if [ $? -ne 0 ] ; then
    echo "git format-patch failed, aborting"
    rm -f $summary
    rm -rf $patches
    exit 1
fi

mv $patches/0000-cover-letter.patch $patches/cover.tmp
awk '/^Subject/ { exit } // { print }' $patches/cover.tmp > $patches/0000-cover-letter.patch
rm -f $patches/cover.tmp

headrev=`git rev-parse --verify HEAD^0`
branch=$(git ls-remote $url | grep ^$headrev | cut -f2 | sed 's%refs/heads/%%')

echo "Subject: [pull request] Pull request for branch $branch" >> $patches/0000-cover-letter.patch
echo "" >> $patches/0000-cover-letter.patch
cat $summary >> $patches/0000-cover-letter.patch
echo "" >> $patches/0000-cover-letter.patch
echo "Thanks," >> $patches/0000-cover-letter.patch
echo "-- " >> $patches/0000-cover-letter.patch
git config --get user.name >> $patches/0000-cover-letter.patch

git send-email --quiet --no-chain-reply-to --to $email $patches/*

rm -f $summary
rm -rf $patches
