Hi,

gmngit was failing to export the repo of one of my projects (go-p9p[0]).
Turns out, the crash was in gmnhg, the library used to convert Markdown
to text/gemini, which has been updated since its inclusion in this
project.  I haven't digged in gmnhg history, I can only tell that the
latest version works fine for me; the attached diff updates it and fixes
the trivial API change.  The diff is fairly long due to a `go mod tidy'.

Cheers,

Omar Polo
