py3: fix comparison between int and None
If stop is None, the condition was always false on Python 2, as None compares
smaller than ints. Therefore we make the condition false if stop is None.

initial setup

repository itself is non-readable
---------------------------------
$ hg init no-read
$ hg id ssh://user@dummy/no-read
000000000000
$ chmod a-rx no-read
$ hg id ssh://user@dummy/no-read
remote: abort: Permission denied: *$TESTTMP/no-read/.hg* (glob)
abort: no suitable response from remote hg!

special case files are visible, but unreadable
----------------------------------------------
This is "similar" to the test above, but the directory is "traversable". This
seems an unexpected case in real life, but we test it anyway.
$ hg init other
$ hg id ssh://user@dummy/other
000000000000
$ for item in `find other | sort -r` ; do
> chmod a-r $item
> done
$ hg id ssh://user@dummy/other
remote: abort: Permission denied: '$TESTTMP/other/.hg/requires'
abort: no suitable response from remote hg!

directory toward the repository is read only
--------------------------------------------
$ mkdir deep
$ hg init deep/nested
$ hg id ssh://user@dummy/deep/nested
000000000000
$ chmod a-rx deep
$ hg id ssh://user@dummy/deep/nested
remote: abort: Permission denied: *$TESTTMP/deep/nested/.hg* (glob)
abort: no suitable response from remote hg!

repository has wrong requirement
--------------------------------
$ hg init repo-future
$ hg id ssh://user@dummy/repo-future
000000000000
$ echo flying-car >> repo-future/.hg/requires
$ hg id ssh://user@dummy/repo-future
remote: abort: repository requires features unknown to this Mercurial: flying-car!
remote: (see https://mercurial-scm.org/wiki/MissingRequirement for more information)
