Ah, I was expecting that you would forward-port the conversion, but
yes, that could be painful and error prone.

But given that there are some dependencies on these patches, could you
please use the following alternative procedure for the patches that
touch both code and documentation?

o	Revert only the documentation portion of each commit.  I will
	then merge the partial reverts with the original commits.

o	Apply the documentation conversion.

o	Reapply the documentation portions on top of the conversion.
