Subject: [PATCH 0/4] Hexdump enhancements

From: Alastair D'Silva <alastair@...ilva.org>

Apologies for the large CC list, it's a heads up for those responsible
for subsystems where a prototype change in generic code causes a change
in those subsystems.

This series enhances hexdump.

These improve the readability of the dumped data in certain situations
(eg. wide terminals are available, many lines of empty bytes exist, etc).

The default behaviour of hexdump is unchanged, however, the prototype
for hex_dump_to_buffer() has changed, and print_hex_dump() has been
renamed to print_hex_dump_ext(), with a wrapper replacing it for
compatibility with existing code, which would have been too invasive to
change.

Alastair D'Silva (4):
  lib/hexdump.c: Allow 64 bytes per line
  lib/hexdump.c: Optionally suppress lines of filler bytes
  lib/hexdump.c: Replace ascii bool in hex_dump_to_buffer with flags
  lib/hexdump.c: Allow multiple groups to be separated by lines '|'
