[R] vi[m] editing of past commands in R command line

[Paul Domaskis]

I've been told that my messages are being rejected because it is being
posted via nabble in HTML format.  I was advised to re-send this
directly to r-help at r-project.org.  My apologies if you get this twice.

When I use bash + readline and ~/.inputrc contains "editing-mode vi",
I can press "v" to switch to from the command line editing to a full
vi session editing of a command.  This doesn't seem to happen in R.
Is there a configuration setting/file that I can set to get this
behaviour?

Furthermore, when using bash, the fc command allows me to edit the
history of commands, and when I exit the editor, all the remaining
(and likely modified) commands are submitted to the bash shell as if I
typed them at the prompt.  Is there a way to get similar functionality
in R?
