R devel - Nov 2002 - [R] CTRL-C suspends echo of shell (R versions 1.6.0 and 1.6.1) (PR#2253)

Problem:
- Shell does not echo anymore 
  after using CTRL-C (to interrupt calculations)
  once during a R session.

Procedure:
- [start session]  R
- [input]          CTRL-C
- [end session]    q()


Some details:
- `stty` before: speed 38400 baud; line = 0; lnext = <undef>;

- `stty` after: speed 38400 baud; line = 0; lnext = <undef>; min = 1; time
= 0;
    -icrnl
    -icanon -echo

I have seen the problem in versions 1.6.0 and 1.6.1, but not in 1.5.1
which I am running on SuSE Linux 7.3. The shell used is bash-2.05.0(1).

Seen here too, but I actually thought it took more to provoke it.
Blind-enter "stty sane" to revert.

(Might this be related to the readline stack issue?)
