* unix/tclUnixChan.c (TclpOpenFileChannel): Added code to regonize
"/dev/tty" (by name) and to not handle it as tty / serial
line. This is the controlling terminal and is special. Setting
it into raw mode as is done for other tty's is a bad idea. This
is a hackish fix for expect SGF Bug #520624. The fix has
limitation: Tcl_MakeFileChannel handles tty's specially too, but
is unable to recognize /dev/tty as it only gets a file
descriptor, and no name for it.
