Printing the chunk again followed by the question can be confusing as
the user has to pay special attention to notice that the same chunk is
being reconsidered.
As we print a long help message if we don't re-display the hunk it ends
up being separated from the prompt. Personally I find the help message
quite annoying when I've fat-fingered the wrong key - I'd prefer a
shorter message pointing to "?" to display more help. We already do
something similar if the user presses a key such as "s" that is disabled
for the current hunk.
It can also be problematic if the chunk is longer than one screen height
because the result of the previous iteration is lost off the screen (the
help guide in the previous example).
To avoid such problems, stop printing the chunk if the iteration does
not advance to a different chunk.

I found the name a bit confusing as we have keys for displaying the
previous hunk and it make me think of that. As it is used to record the
index of the hunk that we've rendered perhaps "rendered_hunk_index"
would be a better name. Also as it needs to hold a negative value we
should declare it as ssize_t like the variables on the line below.

I'd be inclined to leave this line as is to make it clear that the
strbuf is always cleared before adding the keybindings.

style: as you're adding braces to the other clause in this if statement
you should add them to this clause as well.
