git repack and dumb protocols

Hi there,

I've posted a git repository to the web that is an rsync copy of my 
development archive's .git directory, with update-server-info run on it. Now 
if I understand correctly, this contains a single file for every 
commit/file/whatever else I ever made, which is a paint over HTTP. I have then 
recently learned about the wonder that is git repack, which I would love to 
use on this repository, were it not for this comment in its manpage:

8< ----------------------------------------------------------------------
Especially useful when packing a repository that is used for private 
development and there is no need to worry about people fetching via dumb 
protocols from it. 8< 
----------------------------------------------------------------------

It says this relating to the '-a' option, but it makes me wonder if I'll break 
copies of the repo that other people have pulled if I use 'repack'? What are 
the possible interactions and things to keep in mind between repack and dumb 
protocols?

In any case, I would like to suggest that the rather ominous-sounding text in 
the manpage be replaced with something more concrete, i.e. "If you repack an 
archive that has people fetching via dumb protocols from it, X, Y, and Z will 
happen."

Thanks,
Andreas
