R-beta: command-line editing not working in Debian Linux version

I get great flexibility with command-line editing through the "readline" 
library in the "bash" editor and the "ncftp" tool.  S-Plus has this editing 
and I see in the preliminary "Notes on R: A Programming Environment for Data 
Analysis and Graphics", page 65, that "R -e" might give this functionality.  
Typically, one can use either vi or emacs commands to go back through previous 
commands and edit the current command line.

I notice that the readline library is not compiled into the Debian Linux 
R.binary (ldd R.binary).  Perhaps this was an oversight, or perhaps 
command-line editing has yet to be added.

I notice that for vi editing style one ought to set (in "bash" shell)
     export S_CLEDITOR=vi
however, hopefully, the readline [not the S/R readline() function, but the 
readline library] file ~/.inputrc parameters would work to set "vi" mode and 
other readline parameters (if the readline library gives this command line 
functionality in R, that is).
