It would be much better to replace the 'grep -r' by 'find -type f ... |
xargs grep'.  'grep -r' is very bad because:

* '-r' is not standardized

* it can return symlinks which might point to read-only locations
  (e.g. patches/config.sh* are such links).  'sed -i' on such files
  can make the build fail.
