* Command line editing via editline(3) library. * Context sensitive command and file completion, including remote files. Enhancements to auto-fetch feature: * Support for http:// URLs using the http protocol, including proxy HTTP support via $htty_proxy if it's defined. * The connection is kept open between successive files on the same host. (obviously, this does not count for http requests.) * Return value of ftp is 0 on no error, or the offset in argv[] of the file which failed (i.e., argv[x] failed, ftp returns x). * If the path in an ftp URL or classic format line has a trailing '/', cd to the path and enter interactive mode. Fixes [bin/3011], albiet requiring the user to help ftp in determining the operation. Other changes: * '-P port' works for normal ftp, and is the default for all classic style auto-fetch transfers and for ftp URLs that don't specify the port. (previously it would just work for the first xfer.) * Some code moved into separated files along logical divisions. * Editing and completion can be compiled out with -DSMALLFTP.
