Tcsh should not execute characters in the buffer when it encounters
an EOF.
Just imagine that you were typing in a command to the prompt, when
suddenly your connection to the host is broken. You don't want
the incomplete command to be interpreted and executed.
Normal text files, by definition, have newline characters at the
end of each line, including the last one. You can probably configure
your editor to work correctly.
Best regards,
