1. Update the code to the latest from NetBSD, which includes:
* A new command line option to suppress stat(2) errors
* Output is now done via stdio
* Fixes for bitwise OR'ing of letters
2. Andrew from NetBSD merged in our own Johan's readlink patches.
3. Andrew also merged in some brucifications.
I made some small contributions to the header cleanup, and tried
to generally improve the overall style(9)'ishness. I also documented
the new -q option and added the *LINKS to the Makefile.
All responsibility for mistakes in merging the contributions
from the above is mine.
