Also fixes the executable bit; now 644.
Replace tabs followed by xmlstarlet format:

```sh
#!/usr/bin/sh

tmpfile=$(mktemp /tmp/xmlformat.XXXXXX)

sed 's/\t/    /g' ${1} > ${tmpfile} && mv ${tmpfile} ${1}
xmlstarlet fo -s 4 ${1} > ${tmpfile} && mv ${tmpfile} ${1}

rm -rf ${tmpfile} # if something goes wrong
```
