Fix HEADER* and README* wildcards in IndexIgnore
Fix HEADER* and README* wildcards in IndexIgnore

The original intent of HEADER* and README* in the IndexIgnore was
probably to ignore the files that are included at the top (HeaderName) and
bottom (ReadmeName) of the index listing. But the wildcard will hide other
files, like README.txt, so use full filenames instead.
