degesch: fix prompt not showing up after change
When a backlog helper was running and the prompt changed,
it failed to restore within input_rl_show().
Since before input_rl_show() is called the prompt is empty
and in input_rl__restore() it will be changed to the new
version, just skip invoking any Readline functions within
input_rl_set_prompt() when the prompt is hidden. Simple
and straight-forward.
This bug is what I hinted at in the previous commit.
