Hello Craig & Mark,

There's a program called makepatch which does exactly what you want.
Here are the essential contents of makepatch.lha:

 PTool.Library               6604 ----rwed 25-Mar-93
 MakePatch                   1880 ----rwed 11-Feb-93
 MakePatch.doc               2847 ----rwed 29-Mar-93
 PatchEm                     1128 ----rwed 11-Feb-93
 PatchEm.doc                 1961 ----rwed 29-Mar-93

The archive itself is 27677 bytes, since it also contains German
docs and the source code in Assembler.

Here is an extract from the docs:

    MakePatch and Patch'Em are released under the concept of public domain.
The source code in assembly language is included, so feel  free  to  change
these tools and to add useful features.

        WHAT IS IT

    Being a programmer, I often had the following  problem:  I  removed  a
little bug in one of my  programs  and  now  I  had  to  resend  the  whole
program/archive to my beta testers again, though I actually changed only  8
byte.

    This has come to an end - using MakePatch. MakePatch  scans  the  whole
file for changed, inserted or removed byte and saves only these changes, so
that only a very small pachfile will be created.  This  file  contains  all
information for Patch'Em to patch the old version into the  new  one.  This
isn't limited to programs, you may use MakePatch/Patch'Em with all kinds of
data, say graphics, sound, text or lharc-alike archives.


        SYSTEM REQUIREMENTS

    MakePatch works only under Kickstart V37.xxx or later. Additionally the
PTool.Library is required.
