help.c attempts to search for any files that might be in
Documentation/config/, and add them to the help system. Obviously, on vanila
.85, the dir doesn't exist(I just got the error here). It is not a serious
error, as everything else works. I will remove the hard-coded directory, but
right now I can't make a patch. I am fixing/upgrading the debian packages I
maintain.

Txs for the report. Idea: next version don't make an index. It is still
faster at extracting help then sed, even without an index to use. Plus, for
those that are rewriting the config scripts in C, they could use this, and not
have to write it themselves.
