Thanks. This looks very sensible. Some suggested tweaks below (see patch at
bottom).

These were headings like
* Life Cycle
* Adding data to the buffer
Most ended up as ' * *' after the conversion, keeping the extra '*', but
'Adding data to the buffer' didn't.
After patch 4/4 they look the same again, so it doesn't matter.

Makes sense.

Missing period at end of sentence. "*/" should go on the next line.

This snuck up a few lines --- it was between getwholeline_fd and
add_absolute_path before. I think it makes sense for getcwd to be
next to add_absolute_path.

split_* were before this before. Probably launch_editor belongs with
read_file and co instead, but during this conversion it makes sense to
just keep the order from before.

This is something that the flat file format did better. Would it work to
do something similar, for example by dropping the boilerplate comment
before the inline functions (not shown in the patch below)?
