It may be useful to append a suffix denoting the file format. For
example, README.rst is rendered differently when viewed on Github, and
also helps editors to switch to a mode more suitable for the format.
The tests uses a file pattern to find the README file(s) and treats
the one with the shortest name as the main one which must not be
empty.
