Lile a small fast configurable line editing facility
A solution frequently recommended for k and q is rlwrap.
I find rlwrap too big and slow, especially for the tiny, fast k and q interpreters. It feels sluggish.
I have begun experimenting with "lile", a modified version of "ile" which apparently dates back to 1988. I have not seen it discussed anywhere on today's www.
It is small and fast. Custom key commands can be assigned per application using configuration files.
