Thanks for the responses.
I think that the best way to avoid lots of hassle is that people
copy-paste their solutions from their code editor, NOT from R console.
For example, I usually save those solutions for my code archive, and
if I want to run these later on (using Tinn-R), I have to parse ">"
and "+" marks anyway.
I agree entirely but trying to change posting behavior appears to be a
difficult exercise. It would also be much preferred if people would
learn to post the output of dput on an object, rather than what is
displayed on the console when the object is print()ed.

Here's a quick version of CleanTranscript, translated to R:
CleanTranscript <- function(lines) {
lines <- grep("^[[:blank:]]*[^>+[:blank:]]*[>+]", lines, value =
TRUE)
lines <- sub("^[[:blank:]]*[^>+[:blank:]]*[>+] ?", "", lines)
}
So on systems where "clipboard" is supported, executing
source(textConnection(CleanTranscript(readLines("clipboard"))),
echo = TRUE, max.deparse.length=Inf)
will do something similar to what the Windows "Paste commands
only" menu
option does, but you'd need a different incantation on other
systems. And
even this will sometimes mess up, e.g. it will sometimes
misinterpret output
that contains > or + as input.

On Macs (and possibly other *NIXen) the equivalent to reading from
the
"clipboard" is: pipe("pbpaste")
Testing shows that a simple modification after defining
CleanTranscript
produces no error on the example above:
source(textConnection(CleanTranscript(readLines(pipe("pbpaste")))),
+ echo = TRUE, max.deparse.length=Inf)
example(mean)
