# function zfdir {
# Long directory of remote server.
# The remote directory is cached.  In fact, two caches are kept:
# one of the standard listing of the current directory, i.e. zfdir
# with no arguments, and another for everything else.
# To access the appropriate cache, just use zfdir with the same
# arguments as previously.  zfdir -r will also re-use the `everything
# else' cache; you can always reuse the current directory cache just
# with zfdir on its own.
#
# The current directory cache is emptied when the directory changes;
# the other is kept until a new zfdir with a non-empty argument list.
# Both are removed when the connection is closed.
#
# zfdir -f will force the existing cache to be ignored, e.g. if you know
#          or suspect the directory has changed.
# zfdir -d will remove both caches without listing anything.
# If you need to pass -r, -f or -d to the dir itself, use zfdir -- -d etc.;
# unrecognised options are passed through to dir, but zfdir options must
# appear first and unmixed with the others.
