I thought we had agreed that members of R-core are not allowed lives.

As someone who has spent an inordinate amount of time writing and
revising help files, I can assure you that writing help files is about as
difficult of genre as exists. There are numerous constraints which, taken
together, yield no feasible solution.
As you rightly maintain, the help file should be written for people who
may not even know what the purpose of the function is, and for people
who are not native speakers of the language -- rather than just a mnemonic
for the author of the code. On the other hand help files need to be short
because no one reads documentation, and no one squared reads long
Things get even worse for graphics functions -- partly because they are so
complex, and partly because we subconsciously think they should be easy
because we are well tuned to interpreting the graphics themselves.
At heart it seems to me that you are asking for a new form of help file --
taking them from 2 dimensions to 3. For example, the "axis.lty" item in the
barplot help file would look similar "on the surface" to what it
(though perhaps phrased better). But there would be the ability to
the item to learn about axes, line types and possibly other things.
To implement this vague idea, all that needs to be done is for someone to
come up with a workable system, and people to fill in the text.
The big problem that I see with documentation, which you also allude to, is
that the (confused and frustrated) user needs to seek out the appropriate
documentation when trouble happens. Said confused and frustrated user
would rather the documentation came along by itself to say what went wrong.
I'm much more at a loss for this.
