Heya. On p59, this text appears:
There is no direct way to use
save-bufferto copy text into a buffer and specify the name at the same time.
I think this must be a mistake, not in the claim, but in the command given. It’s true that you can’t copy text into a buffer while naming the buffer, but you wouldn’t use save-buffer to do that, right? save-buffer writes a buffer to a file on disk. It’s copy-selection that copies text into a buffer – and sadly it doesn’t take a -b option, which I think is what this is meant to get at.
