I think I found the reason that these lines are printed. Apparently
str.isspace() will return False for empty strings:

print('\t'.isspace())
True
print('\n'.isspace())
True
print(''.isspace())
False

With these lines added before the check:

+                if (amsnippet1 + amsnippet2) == '':
+                    print('EMPTY:')
+                    print(str(module))

And running the Emacs script again:

$ env GNULIB_TOOL_IMPL=py ./admin/merge-gnulib  | grep -A2 EMPTY:
EMPTY:
manywarnings
EMPTY:
warnings

Which matches the added lines in the diff. I've changed those
conditions to the following:

   if (amsnippet1 + amsnippet2).strip() != '':
