Hi - this kind of sank without a trace last time I posted it, and it's
been a couple of months, so I thought I'd post it again to see if there
was any interest this time around. Apologies if this is considered bad 
manners.

Subject: patch: make hexl mode support 8, 32 and 64 bit groups

The hexl binary supports 8, 16, 32 and 64 bit groups, but hexl mode
currently only supports 16 bit groups.

This patch adds support (controlled by a custom item, `hexl-bits')
for the other group sizes.

Oh, and there was a minor bug in hexl-scroll-up (and -down) which meant it
scrolled by one line too many (didn't take account of the ruler line) by
default, so you'd miss one line of data if you weren't careful.

Change log entry included.
