Details:

It seems that in findutils 4.5.11 the find -perm +mode has broken (with a
numerical mode). -perm /mode is still working as expected and as before.

See this example:

$ mkdir /tmp/foo
$ touch /tmp/foo/bar
$ chmod u+x /tmp/foo/bar

$ find --version | head -1
find (GNU findutils) 4.4.2
$ find /tmp/foo -perm +0100
/tmp/foo
/tmp/foo/bar
$ find /tmp/foo -perm /0100
/tmp/foo
/tmp/foo/bar

$ find --version | head -1
find (GNU findutils) 4.5.10
$ find /tmp/foo -perm +0100
/tmp/foo
/tmp/foo/bar
$ find /tmp/foo -perm /0100
/tmp/foo
/tmp/foo/bar


$ find --version | head -1
find (GNU findutils) 4.5.11
$ find /tmp/foo -perm +0100
$ find /tmp/foo -perm /0100
/tmp/foo
/tmp/foo/bar

Note that with version 4.5.11, -perm +0100 returns no files, even though there
is an executable directory and file present.
