Error when using the logo lua 5.3.4

[Ola Zetterqvist <olab@...>]

Hi,

Has created a license and version information page for my program but
there were problems with lua5.3.4 doc file "logo.gif".

Dragging the file to a web browser so it does not seem to have the right view about the file,
Firefox can do it best, but shows odd things, believe it is a png image.

Also when to Save_as becomes double suffix logo.gif.png

Have also been tested in Linux, when you open the file (double-click) so says the
"File does not appear to be a GIF file"

(lua-5.3.4.tar.gz is downloaded from LUA site)

Best Regards,
Ola Zetterqvist
