+       * nano.h, files.c, nano.c: Adding the command-line option --noread
+       to treat any name on the command line as a new file.  This allows
+       nano to write to named pipes -- it will start with a blank buffer,
+       and will write to the pipe when the user saves the file.  This way
+       nano can be used as an editor in combination with for instance gpg
+       without having to write sensitive data to disk first.

        * src/*.c: More editing of comment blocks and trimming of blank lines.
