Yes, or we could go the whole hog and have a total of 4 functions:

(1) For users that want to use a short version, and are fine with
the default values for the grouping / other parameters -- also have
both the print_to_buffer/sprint_hex and print_to_console/hex_dump
variants.

(2) For users that care about these parameters, both the variants
with the expanded arglist (the ones listed above in (1) would then
just be inlines wrapping over these ones)

Just that it would be nice if there is some simple (with short arglist)
function that works well-enough for most people that everyone would
be able to adopt/use quickly.
