No real need for html output. I suspect that a big title like the
above would cause troubles for pdf output. That's basically why I opted
to break it.

Yet, if you prefer, I'll keep it as-is.

This was unintentional. I probably hit <enter> by mistake on that line.

I'll revert.

Probably because the number of changes were bigger than 50%. The algo
there seems to be dumb. I suspect that adding whitespace/tabs on lines
makes it to consider the entire line as different.

git log -M10 would change the threshold to 10% similarity and will
likely show it as a rename. I'll use -M on the next version for this
patch.

Yes. Patch 56 renames almost all Documentation/*.txt to .rst. Those files
are already parsed properly by Sphinx, so no changes there are needed.

I'm working on followup patches (not submitted yet), with moves all
ReST files under Documentation to some place.

In the specific case of those files, on the series I'm working,
I moved them to be part of the driver-api:

https://git.linuxtv.org/mchehab/experimental.git/commit/?h=convert_rst_renames&id=3387ab063cf43f91d5c0f79d741244e7dbcdec05

The results, when parsed, are at:

https://www.infradead.org/~mchehab/rst_conversion/driver-api/vfio.html
https://www.infradead.org/~mchehab/rst_conversion/driver-api/vfio-mediated-device.html

Thanks,
Mauro
