Dear Maintainer, rlwrap misbehaves when combined with readline 8.1, as described in https://github.com/hanslub42/rlwrap/issues/108 The issue has been fixed; the fix is available in Debian testing, in rlwrap version 0.46 rlwrap also works fine with older versions of readline; just this particular combination of version is broken. The github bug report provides a compatibility matrix, of what works with what. I'm mildly confused, because I use rlwrap regularly, but only spotted this bug a few days ago. (I also use multiple OS'es so maybe I just never noticed the problem w/ Debian before? ???) T'would be nice to have a compatible rlwrap/readline pair.
