The control -D character must b prevented from reaching the history
The program must be able to receive a `\n' by itself in order to
function properly.
You can see it at http://www.hurontel.on.ca/~barryp/ed
Here is the code in question!
char *
rl_gets ()
{
register int i = 0;
/* If the buffer has already been allocated, return the memory to
the free pool. */
if (line_read)
{
free (line_read);
line_read = NULL;
} /* Get a line from the user. */
line_read = readline ("");
/* If the line has any text in it, save it on the history.
The control -D must be intercepted here */
if (line_read && *line_read)
add_history (line_read);
/* copy the line so ed can read it as if from stdin */
for (; i <= temp_len; i++)
templine[i] = '\0';
strcpy (templine, line_read); /* so get_tty_line can use the line */
strcat (templine, "\n"); /* for histfilename */
temp_len = strlen (templine);
return line_read;
}
