Hello Lynx-dev,
I have made a patch to add support for Gopher's "hURL" functionality.
The patch is attached and applies to "src/LYGetFile.c". I'm not
well-versed in the C language so forgive me if I've made any errors.

See also: The thread "[Lynx-dev] Extend gopher client functionality to
support URL scheme" from May 2016 on this very mailing list.
