```
server.Server.save_buffer(self, name: Option<&str>, path: impl AsRef<Path>) -> Result<(), Error>
```

Write a paste buffer to a file, letting tmux do the writing.

The counterpart to [`Self::load_buffer`], and the same reasoning: the
bytes never cross a command line, so a buffer larger than an argument
can hold still round-trips. tmux writes as the user running the
server.

# Errors

Returns an error when the buffer is missing or tmux cannot write the
path.
