[Lynx-dev] Potential bug in forms

Hello,

I think I may have found a bug in the way Lynx submits forms. While testing a
personal website for text-only compatibility I came across an issue where a
form that I use to send an empty POST request is actually sending a GET request
but only in Lynx. I discovered that this happens consistently with any form
containing only a single input element. Adding a second input of any kind
results in the form being submitted correctly in Lynx.

To help recreate this, I have attached a small web server written in python3
demonstrating the requests sent from two example forms.

Additionally, here is the output of `lynx -version` in case that is useful:
Lynx Version 2.9.0dev.10 (11 Aug 2021)
libwww-FM 2.14, SSL-MM 1.4.1, GNUTLS 3.7.2, ncurses 6.2.20210905(wide)
Built on linux-gnu.

Best,
Adon
