This is one of those repo snapshot tarballs that GitHub automatically
generates when you make a new tag or release. I think we should use
'fmt-3.0.1.zip', because that was prepared specially for the release by
the upstream maintainers.

I'd leave "safe" out of the synopsis. Like saying it's "different" or
"secure", it's only meaningful when we say what it's safe from. For
example, safe from a wildebeest stampede, or from printf format-string
attacks ;) There's space for this in the description.
