Is there another new solution for this issue?
especially I would like to use:

the use of this is suggested in the completion.r file of utils:

## test some typical completion attempts
testLine <- function(line, cursor = nchar(line))
     str(utils:::.win32consoleCompletion(line, cursor))


(full quote because of the age of the tread)

Kind regards Knut
