@defvar find-file-literally
This buffer-local variable, if set to a non-@code{nil} value, makes
@code{save-buffer} behave as if the buffer were visiting its file
literally, i.e. without conversions of any kind. The command
@code{find-file-literally} sets this variable's local value, but other
equivalent functions and commands can do that as well, e.g.@: to avoid
automatic addition of a newline at the end of the file. This variable
us permanent local, so it is unaffected by changes of major modes.
