[[<-.data.frame with POSIXt replacement (PR#4808)

Hi,

The following seems to be a bug introduced with version 1.8.0 (it worked
without error on my installation of version 1.7.0):

test <- data.frame(time = I(c("2003-08-19:22:55:57")))
test[["time"]] <- strptime(test[["time"]], format =

"%Y-%m-%d:%H:%M:%S")
Error in "[[<-.data.frame"(`*tmp*`, "time", value =
strptime(test[["time"]],  : 
	replacement has 9 rows, data has 1

## This generates the same error:
# test$time <- strptime(test$time, format = "%Y-%m-%d:%H:%M:%S")
