Thanks, but since I'm using a recent snapshot (2000-Jan-14) what I'm
seeing must be different.  The value of "tty" in CYGWIN did not
affect the problem I reported.  Again, what I am seeing is that
line editing works when running inside a console, but within
rxvt line editing does not work.

After poking around in the source, I was able to make a patch that
fixes the problem I'm having.  I won't be surprised if there is a
better way of doing this, but this does fix the problem:

 {
-  line_edit ((char *) ptr, len, 1);
+  line_edit ((char *) ptr, len /*, 1*/);
   return len;
 }

Having always_accept (the 3rd arg to line_edit) set to 1 prevents
pseudo-terminals from having line editing.  I'm not sure what was
intended here.
