changes:
- Finish migrating zic to its own private.h.
- Fix zic.8 so that it really is written in -mdoc.
- Add four new flags to zic (&document):
-D don't create directories
-u change ownership of newly-created files to user
-g change ownership of newly-created files to group
-m change mode of newly-created files to modespec
These, once proven, can be used to clean up the installation.

insane otherwise.
