[svn] Fixes by Christian Biere:
* progress.c (bar_set_params): Fixed syntax error when HAVE_ISATTY
was undefined.
* ftp.c (ftp_loop_internal): Allocate a larger buffer in case
"try" gets translated to something large.  Ditto in http_loop in
http.c.
* http.c (response_header_copy): Don't write to buf[BUFSIZE].
* ftp-opie.c (skey_response): Eliminate unnecessary string
concatenation; just call gen_md5_update twice.
