evolve: remove the unnecessary condition to check empty successors set

I annotated the history of this "newer == [()]" condition and found
that it was added in the initial stages of evolution project (more than
8 years ago) and there is no test where we get [()] as a successor set.

So looks like "if not newer" is enough to check if it is empty.
I also looked into obsutil.successorssets() implementation and
I don't think it would give us [()] in any case.

import sys

formatted_args = []

UNSAFE_CHARACTERS = [" ", "!", "\"", "#", "$", "&", "'", "(", ")", "*", ",", ";", "<", ">", "?", "[", "\\", "]", "^", "`", "{", "|", "}", ":", "~", "/"]


def find_unsafe(arg):
    for unsafe in UNSAFE_CHARACTERS:
        if unsafe in arg:
            return True

    return False


for arg in sys.argv[1:]:
    if find_unsafe(arg):
        formatted_args.append('"%s"' % arg)
    else:
        formatted_args.append(arg)

print("$ " + " ".join(formatted_args))
