Hi Kyle,

guix shell r

and then

will get you the C-c handling you want.

There is indeed readline support with guix shell r -- R:
up arrow to get history, c-E, c-A for end of line, start if line, etc.

I think maybe the problem lies not with readline but with the way
signals are handled. I can't seem to understand exactly how, but I would
look into that direction.
