Hi,

Enclosed is a patch to mandocdb(8) that lists index filenames relative 
to their database directory instead of absolute.

In other words,

   /usr/local/man/man1/foo.1 -> man1/foo.1

This frees up a lot of space in the databases and also allows whole 
subtrees to move around with `cp -R'.

While here, I made chdir() error out since it's now required to traverse 
the paths.  I also touched up this and that, and removed some missed 
"verb > 2" statements.

apropos(1) and whatis(1) work fine with this patch (except my 
"interactive mode" posted to discuss@, eagerly awaiting your comments), 
but catman(8) and man.cgi(7) will need adjustment.

Thoughts?
