Added forgotten share/doc/psd/05.sysman and share/zoneinfo/America/Indiana.
bsd.doc.mk:
Nuked mkdir -p and wrong fixups of the leaf directory's ownerships and
permissions. The doc tree should be well enough established for this
to be safe. Installs to directories should use a trailing slash on
the directory name so installs to non-drectories are fatal, but I
didn't start changing them.
bsd.man.mk:
Nuked mkdir -p and wrong fixups of the leaf directory's ownerships and
permissions. They were overkill to create just /usr/share/info.
zoneinfo/Makefile:
No changes yet. zic creates directories with ordinary 755 permissions.
Why do we use 555 permissions for directories in /usr/share/zoninfo.
Why not for zoneinfo itself? /proc and /dev/fd are the only other
directories in the system with 555 permissions.
Fixes bugs in the latter: the `all' target was never up to date; there
was no `depend' target. Doesn't work for multiple info files because
it leverages bsd.doc.mk and that is broken. Info should be installed
more like man pages...
