Actually, I think both Martin and I use reaadline R versions on a daily basis (Linux and OSX Terminal respectively). For my case, it is just that I rarely use the backwards search feature and I'm old enough that terminal widths other than 80 look odd to me so I don't resize much either. Of course that doesn't mean that the bugs aren't annoying to others!
