	ExeCtE()
	This function executes a ^E (control-E or caret-E) command,  which
returns the value of the form feed flag.  The form feed flag is -1 if the
last read operation was terminated because a form feed was encountered.  It
is 0 otherwise.  If the ^E command is preceded by a numeric argument, then
the command sets the value of the form feed flag.  The form feed flag is
used by the output code to indicate whether a form feed should be appended
when the edit buffer is written to the output file.
