...atches adds a signal handler for SIGWINCH (which GNU Readline stopped handling a few years ago without telling anyone). There is no other use of SIGWINCH in the R code so I don't think this will cause problems. This makes terminal-resizing possible. The other one adds some additional cleanup to popReadline. Now, popReadline is called every time a command is entered at the prompt, or when R catches SIGINT, to reset the terminal settings and take control back from Readline. My second patch fixes incremental-search by amending popReadline to clear the line state as well. I invite creative suggestions as...

Hi Peter, Martin, and others, Thanks for your replies. - The bugs apply to all systems that use GNU Readline, not just Linux or Arch Linux. - Readline version 6.3 changed the signal handling so that SIGWINCH is no longer handled automatically by the library. This means it's not currently possible for people using R on e.g. Linux to resize the terminal, or at least when they do so
