Emacs to create new files with the Unix-style convention of using
newline at the end of a line. @xref{Coding Systems}.
-@vindex file-name-buffer-file-type-alist
-@cindex binary files, on MS-DOS/MS-Windows
- Some kinds of files should not be converted at all, because their
-contents are not really text. Therefore, Emacs on MS-Windows distinguishes
-certain files as @dfn{binary files}. (This distinction is not part of
-MS-Windows; it is made by Emacs only.) Binary files include executable
-programs, compressed archives, etc. Emacs uses the file name to decide
-whether to treat a file as binary: the variable
-@code{file-name-buffer-file-type-alist} defines the file-name patterns
-that indicate binary files. If a file name matches one of the patterns
-for binary files (those whose associations are of the type
-@code{(@var{pattern} . t)}, Emacs reads and writes that file using the
-@code{no-conversion} coding system (@pxref{Coding Systems}) which turns
-off @emph{all} coding-system conversions, not only the EOL conversion.
-@code{file-name-buffer-file-type-alist} also includes file-name patterns
-for files which are known to be Windows-style text files with
-carriage-return linefeed EOL format, such as @file{CONFIG.SYS}; Emacs
-always writes those files with Windows-style EOLs.
-
- If a file that belongs to an untranslated file system matches one of
-the file-name patterns in @code{file-name-buffer-file-type-alist}, the
-EOL conversion is determined by @code{file-name-buffer-file-type-alist}.

- On MS-DOS and Microsoft Windows, Emacs guesses the appropriate
-end-of-line conversion for a file by looking at the file's name. This
-feature classifies files as @dfn{text files} and @dfn{binary files}. By
-``binary file'' we mean a file of literal byte values that are not
-necessarily meant to be characters; Emacs does no end-of-line conversion
-and no character code conversion for them. On the other hand, the bytes
-in a text file are intended to represent characters; when you create a
-new file whose name implies that it is a text file, Emacs uses DOS
-end-of-line conversion.
-
-@defvar buffer-file-type
-This variable, automatically buffer-local in each buffer, records the
-file type of the buffer's visited file. When a buffer does not specify
-a coding system with @code{buffer-file-coding-system}, this variable is
-used to determine which coding system to use when writing the contents
-of the buffer. It should be @code{nil} for text, @code{t} for binary.
-If it is @code{t}, the coding system is @code{no-conversion}.
-Otherwise, @code{undecided-dos} is used.
-
-Normally this variable is set by visiting a file; it is set to
-@code{nil} if the file was visited without any actual conversion.
-
-Its default value is used to decide how to handle files for which
-@code{file-name-buffer-file-type-alist} says nothing about the type:
-If the default value is non-@code{nil}, then these files are treated as
-binary: the coding system @code{no-conversion} is used. Otherwise,
-nothing special is done for them---the coding system is deduced solely
-from the file contents, in the usual Emacs fashion.
-@end defvar
-
-@defopt file-name-buffer-file-type-alist
-This variable holds an alist for recognizing text and binary files.
-Each element has the form (@var{regexp} . @var{type}), where
-@var{regexp} is matched against the file name, and @var{type} may be
-@code{nil} for text, @code{t} for binary, or a function to call to
-compute which. If it is a function, then it is called with a single
-argument (the file name) and should return @code{t} or @code{nil}.
-
-When running on MS-DOS or MS-Windows, Emacs checks this alist to decide
-which coding system to use when reading a file. For a text file,
-@code{undecided-dos} is used. For a binary file, @code{no-conversion}
-is used.
-
-If no element in this alist matches a given file name, then
-the default value of @code{buffer-file-type} says how to treat the file.
