Is there any way to get zlib to just generate a suggested dictionary from

No, I asked the author. Apparently it is a hard problem, there have
been research papers written about it.
Shawn has a Perl script that makes a guess at a dictionary. That
scripts gets 4-7% improvement. The number one thing that ended up in
the Mozilla dictionary was the five different license versions that
had each been copied into 50,000 files over time.
for the mozilla project it may make sense to feed all these license files from
all over as one string to git, as an exception to your normal process of going
file by file. if you can do this then the delta functionality should reduce
these files to practicaly nothing.
