[pkg-lynx-maint] Bug#1116319: lynx: formats <form method=post enctype=text/plain> wrong

[наб]

Package: lynx
Version: 2.9.0dev.12-1
Version: 2.9.2-1
Severity: normal
Tags: upstream

Dear Maintainer,

If you submit
	<form method=post enctype=text/plain>
		<input type=text   name=vendor  value=http                  hidden readonly>
		<input type=text   name=archive value=yes-i-really-want-one hidden readonly>
		<input type=submit name=type    value=tar>
		<input type=submit name=type    value=zip>
then lynx does
	1477722 write(3, "POST /src HTTP/1.0\r\nHost: nabijaczleweli:8000\r\nAccept: text/html, text/plain, text/sgml, text/css, */*;q=0.01\r\nAccept-Encoding: gzip, bzip2\r\nAccept-Language: en\r\nPragma: no-cache\r\nCache-Control: no-cache\r\nUser-Agent: Lynx/2.9.2 libwww-FM/2.14 SSL-MM/1.4.1 GNUTLS/3.8.5\r\nReferer: http://nabijaczleweli:8000/src\r\nContent-Type: text/plain\r\nContent-Length: 56\r\n\r\nvendor=\nhttp\n\narchive=\nyes-i-really-want-one\n\ntype=\ntar\n", 415) = 415
which is wrong: the correct body is
	vendor=http\r
	archive=yes-i-really-want-one\r
	type=tar\r
as per
	https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#submit-body
	https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#text/plain-encoding-algorithm

I repro this on upstream lynx 2.9.2.

Best,
