Easier diff check for Issue 5309

Easier diff check for Issue 5309

This is not the actual patch
but simply the diffs of the
files that changed.

As these are snippets and as
they were all autogenerated,
I had to edit the snippet and
copy then to ../snippets/new/..
so they get generated by
the doc build into ../snippets/..
correctly.

However that meant all these files
were 'new' and so diffing them visually
would be hard.

This 'rietveld' is to help with that.
