  . t)

Documentation

Alist used in the past for distinguishing text files from binary files.

Each element has the form (REGEXP . TYPE), where REGEXP is matched against the file name, and TYPE is nil for text, t for binary.

This variable is deprecated, not used anywhere, and will soon be deleted.

Probably introduced at or before Emacs version 24.4.
