site-book/src/test/resources/test-fix-md.txt

The problem #5 (rewrite_relative_links) is particularly tricky, so this test file
allows you to test it.  Run 
`cp src/test/resources/test-fix-md.txt.stat src/test/resources/test-fix-md.txt`
then
`awk -f bin/fix-md-dialect.awk src/test/resources/test-fix-md.txt`
The .txt file will be re-written in place.  You can check the results by comparing
the "Should be..." lines with the lines above them.  Contrast with the original
.stat file to see before re-write.
