Actually -- on the same track but even better: if you are using a
unixy system, you are likely to have all the users belong to a group,
and the files are editable by the group because they are rwx by group
members.

So write your own "git-lock" command that does "chmod g-w $@";
git-unlock reenables the group-writable bit. Done.

For more arcane things, use ACLs. On Windows I am sure there is a
commandline tool to touch ACL bits.
