Check the behavior before the patch:
cd documentation && make pdf
Go to Chapter 8 Desktops Environments.
Check the broken links in 8.1 Synopsis.
Then do
cd documentation && make run
Access to http://localhost:1313/ and check that the same links work in both
"Split HTML and Single HTML.
After applying the patch, do the same tests to check the links work in the three
different output formats.
Once this is in the tree I will commit another change clarifying the usage of
the link macros.
