Given print_hex_dump() operates on entities of groupsize (1, 2, 4, or 8)
bytes, wouldn't it make more sense to consider repeated groups instead
of repeated bytes?

Using a custom message instead of just "*", like "hexdump" uses, will
require preprocessing the output when recovering the original binary
data by feeding it to e.g. "xxd".
This may sound worse than it is, though, as I never got "xxd" to work
without preprocessing anyway ;-)
$ cat $(type -p unhexdump)
#!/bin/sh
sed 's/^[0-9a-f]*//' $1 | xxd -r -p | dd conv=swab
Gr{oetje,eeting}s,
