We have something which is (in the eyes of all who played along here) better
and simpler.  Instead of passing an explicit option down (which has to cope
with the different entry paths for this), the install function now checks for
group-write mode of the target target directory. If present, the installation
will use group-write too on file and its new directories.  Easier, and quite
elegant.  Have a go and see if it fits your bill -- no umask fiddling, no
teaching all users to change habits, no inotify.
