And @LudwigOrtmann: A diff you do best in GitHub md with
```
```diff
-       rm -rf $(PKG_NAME)
+       cd $(PKG_NAME) && \
+               git clean -x -f && \
+               git reset --hard $(VERSION)
```
```
which results in 
```diff
-       rm -rf $(PKG_NAME)
+       cd $(PKG_NAME) && \
+               git clean -x -f && \
+               git reset --hard $(VERSION)
```
Then I don't accidentally ignore the '-' at the start of the line and get confused ;-)
