I might be wrong, but I had guessed that the OP had meant that in the
sense of "a beginner might think this would work, so maybe we should
explicitly point out that it doesn't".

Of course, a) I may be wrong and 2) this may be in that blurry area
between the worth-mentioning and the
too-obvious-if-you-actually-read-the-docs camps...

ah, that would make more sense.  In that case, sending a patch is
much better. :)

Bingo.

By definition beginners don't know how to send patches. So incorporate
that fleeting beginners view, with appropriate cometary of the pros
added, while it's still hot.  By the time I know how to send patches,
the rare glimpse into the beginner's head will be gone. Besides, I
Plus a full patch would imply I already knew the expert commentary
part -- imagine that, an expert still able to come up with beginner
glimpses. Actually in a past life I sent patches. That isn't the point
though.

i don't see how patches has anything to do with beginners.  You
can obviously put sentences and paragraphs together, so rewrite
the part of the answer you think should change, then post it.

Otherwise, it just ends up in my queue with all the other things
that wait for airport layovers.  Things that require less work,
like patching or cutting and pasting, get done faster. :)

OK. Please make this the new result of

I won't be making this change.  I thought you had said that that
method was an example of what not to do, but your one line change
suggests that they use it.  I don't think it improves the answer 
at all.
