When using GH_TAGNAME the DISTNAME would have GH_PROJECT and GH_ACCOUNT in
it. When not using GH_TAGNAME it would not have this. Now both cases
will add in the GH_PROJECT and GH_ACCOUNT.
Add special care to ensure that the DISTVERSION is not added in twice. If
a port does GH_TAGNAME=v${PORTVERSION} it will be added in twice though. For
that case DISTVERSIONPREFIX=v should be set and no GH_TAGNAME should be used.
empty() is used rather than (!defined || !${}) to support fmake.
The purpose of setting DISTNAME at all in these cases is to make it more clear
that the distfile is from *GITHUB* and to avoid collisions if a project were
to be renamed or moved. Without adding in GH_PROJECT and GH_ACCOUNT then there
are real risks that collisions on filenames would happen on renamed or moved
projects, which is fairly common. A GITHUB-generated file may not match
a custom-rolled or git-archive-rolled distfile.

SIXEL is one of image formats for terminal imaging introduced by DEC VT series.
Its data scheme is represented as a terminal-friendly escape sequence.
So if you want to view a SIXEL image file, all you have to do is "cat" it to
your terminal.
