Sure, just drop a script called `git-sage-patch` somewhere in your $PATH.
Here's such a script::
#!/bin/bash
# Script to produce a patch to the Sage library.
# Usage:
# git sage-patch filename.patch "commit message"
echo "# HG changeset patch
# User $(git config user.name) <$(git config user.email)>
# Date $(date +%s) 0000
$2
" > $1
git diff upstream/master HEAD >> $1
Disclaimer: this script is not very robust and fails with a cryptic
error message if you use it somewhere other than inside the Sage library
repo, or don't provide it the correct command line arguments. It also
doesn't check that the filename exists before exporting the patch. Use
with caution! :)
