+ Added listing files to the set of non-"binary" (text, Stream_LF)
+ files. (Wget works either way, but other programs, like, say, text
+ editors, work better on listing files which have text attributes.)
+ Now we use "binary" attributes for a binary ("IMAGE") transfer,
+ unless "--ftp-stmlf" was specified, and we always use non-"binary"
+ (text, Stream_LF) attributes for a listing file, or for an ASCII
+ transfer.
+ Tidied the VMS-specific BIN_TYPE_xxx macros, and changed the call to
+ fopen_excl() (restored?) to use BIN_TYPE_FILE instead of "true".
