evolve: Fix crush when reading docstring
Before this patch, hg evolve --divergent could crush when looking
for docstring of function of merge.update. We were checking the
docstring to work properly with older version of Mercurial. It
could crush if an extension would wrap merge.update without
keeping the docstring. This patch fixes the crush.
