0.95    First release

0.96	Add reference to RFC1945. Correct some resource URLs.

	Note that HTTP/0.9 servers not handled.

	Bound sock_getline loop by buffer length.

	Print warning if actual length != content length.

	Return non-zero status if failed to fetch document.

	Identify user agent as HTGET-DOS to avoid confusion with
	other HTGET.

0.97	Add -v flag to print some progress messages.

	Add -p ident:password to allow authorisation to be sent.

0.98	Add -o filename option to save to a file.

	Add -m to send If-Modified-Since with date of file in -o.

	Use getopt instead of doing argument parsing oneself.

0.99	Provide a manual page.

	Bug fix: if no Content-Length line, read until EOF

	Disable -m if -h specified. It will be ignored by the server
	anyway.

	Warn if continuation line seen. Fortunately the only header
	line we are interested in, Content-Length, is very unlikely
	to span lines.
