Andrey Lushnikov 337315c5fe [doclint] remove preprocessor's gen:copy and gen:paste commands
These commands proved to be over-complicating the documentation source.
We should keep documentation source as simple to edit as possible to
make it friendly to contributions.

This patch keeps the gen:version command as it is non-invasive.
