I had forgotten that particular annoyance, but that was another
reason I stopped using FTP interactively (to retrieve several
I-Ds in sequence) rather than the editor macros, which still
work fine for single I-D retrievals if am can sure I know what
the name, including version number, is.   I don't know what
Lyndon is doing but, while five minutes seems a tad long, 20
seconds is too short to retrieve something, think for a bit, and
then issue another command... and probably too short for clients
in many environments to perform "mget" by sending NLST, getting
back a list of names, builting a mini-script, and then start
sending RETR commands.
