Something that I think is a flaw in the Gemini specification is that it
cannot make a preformatting block containing a line with ``` at first.

One way to fix this is to allow preformatting starting with more than
three back ticks and if so then the end also has the same number of back
ticks; this means that it must keep track of how many back ticks, instead
of merely on/off, only.

Usually, most files will not need this, but sometimes it might be needed.

Nice catch. This issue also isn't yet covered in the discussion of the
BNF. I like your proposition of using more ticks when needed (similar to
CommonMark). It would mean to loosen the spec, though:

| It is possible to unambiguously determine a line's type purely by
inspecting its first three characters.

Thus, from a practical point of view, my personal approach would be to
work around in editing and indent the whole preformatted text by a fixed
set of spaces (and mention this in the alt-text).

Alternatively offer the preformatted content as an extra text/plain file
or the whole content in a different format, altogether.

As an aside: Should gemtext support its line types within > quote lines?
Again, personally, I'd prefer sticking to the "first three char" rule.

Cheers
