Adding Diff syntax highlighting to Sublime Text

My chosen colour scheme for Sublime Text doesn’t include support for diff/patch files, so I added my own.

To the bottom of my .tmTheme file, I added this just above the closing </array>:

        <dict>
            <key>name</key>
            <string>diff.header</string>
            <key>scope</key>
            <string>meta.diff, meta.diff.header</string>
            <key>settings</key>
            <dict>
                <key>foreground</key>
                <string>#009933</string>
            </dict>
        </dict>
        <dict>
            <key>name</key>
            <string>diff.deleted</string>
            <key>scope</key>
            <string>markup.deleted</string>
            <key>settings</key>
            <dict>
                <key>foreground</key>
                <string>#DD5555</string>
            </dict>
        </dict>
        <dict>
            <key>name</key>
            <string>diff.inserted</string>
            <key>scope</key>
            <string>markup.inserted</string>
            <key>settings</key>
            <dict>
                <key>foreground</key>
                <string>#3333FF</string>
            </dict>
        </dict>
        <dict>
            <key>name</key>
            <string>diff.changed</string>
            <key>scope</key>
            <string>markup.changed</string>
            <key>settings</key>
            <dict>
                <key>foreground</key>
                <string>#E6DB74</string>
            </dict>
        </dict>

This sets up a green colour for the meta information, blue for added lines, red for deleted lines and a yellowish colour for changed.
