This sounds related to the buggy prompt display code. There is a known
issue in readline where some (but not all) prompts cause display problems,
because the display engine isn't properly accounting for invisible
characters in the string, and I am awaiting a patch from the upstream
maintainer. In the meantime, I was unable to reproduce the symptoms;
could you please let me know what your $PS1 variable is?
