[bugfix] Fix setup.read_desc() regex

If a space was behind a sphinx link and the link was different from
the label, the link was removed but the alignment does not match the
previous line. Modify the regex pattern to remove a following space
in such case.

Also test the long_description created by setup.py in make_dist.py
script
