Startup time ~4 s on nvim, macos, even with empty init.lua

Turned out to be asdf's extremely slow performance (even though it's not slow on the command line).
See asdf-vm/asdf#290 for details.
Workaround is to add this to .bashrc:

function unshim() {
  PATH=$(asdf where golang)/go/bin:$PATH
}

I've had related problems before and asdf's direnv plugin works too.

startuplog had weird output, so finding this was mostly an educated guess and lots of echomsg statements (with reltime).
