Subject: [PATCH] Eliminate duplicate traversal of directories in realinstall
 target.

This change eliminates O(2^N)-1 passes through the individual documents,
where N is the number of levels of directory hierarchy.  For a
"make install" from the top level of the doc/ tree, files corresponding
to individual documents were being installed eight (!!!) times.
