# function zfcget {
# Continuation get of files from remote server.
# For each file, if it's shorter here, try to get the remainder from
# over there.  This requires the server to support the REST command
# in the way many do but RFC959 doesn't specify.
# Options:
#   -G   don't to remote globbing, else do
#   -t   update the local file times to the same time as the remote.
#        Currently this only works if you have the `perl' command,
#        and that perl is version 5 with the standard library.
#        See the function zfrtime for more gory details.
