This is your not quite correct interpretation.
The R internal manual you mention below talks about TABs in
specific places in *.Rd files only.
*.R (and *.c even more) use TABs in many places, and all of R core have
their Emacs / vi / ... settings accordingly.
Happy New Year, indeed, to all contributors and readers of 'R-devel'!
