lukem b918fc0803 Forbid filenames returned from mget that aren't in (or below) the
current directory.
The previous behaviour (of trusting the remote server's response when
retrieving the list of files to mget with prompting disabled) has been
in ftp ~forever, and has been a "known issue" for a long time.
Recently an advisory was published by D.J. Bernstein on behalf of
Yosef Klein warning of the problems with the previous behaviour, so
to alleviate concern I've fixed this with a sledgehammer.

Remember the local cwd after any operation which may change it.
Use "remotecwd" instead of "remotepwd".
