I guess what's confusing is the talk about token types, which is are
apparently something specific to Fish and not explained in the manual.
Why doesn't the message just say
fish: Expected redirection specification, got "\n" (newline)
echo > (echo)
^
or
fish: Invalid file name "" for output redirection
echo > (echo -n)
^
I think the error message repeats the problematic token so that the
user can see it. If it said 'Can't redirect to ""', the user would
wonder which part of the command she typed produced the "". But the
message needs to say that the token expands to "" or to newline, which
are invalid file names. And it does not need to mention tokens.
What do you suggest the messages should be?
