[Bug-readline] Possibility of retrieve time/date of each command

[Simón]

Hi,
    I use lftp 4.3.3 and it uses readline to save a log with the list 
of commands executed. I would like that this list saves too the 
date/time of that commands.
    I report this to lftp developer and he says that I address this 
feature request to readline developers.
    Is possible this feature?
    Regards.
