Hi again,
Sorry, I don't know why, but I missed this part of your answer:

But I want the same effect than
chown me: /tmp/bla
so changing:
(1) the owner of /tmp/bla to user "me"
(2) the group of /tmp/bla to the login-group of user "me"
chown me /tmp/bla
should only do (1), no ?

Yes, but when you execute:
chown me: /tmp/bla
as group is '' as well and it is not a problem.
I don't see any problem / ambiguity in allowing both:
chown me: /tmp/bla
chown 1001: /tmp/bla
especially as:
chown me /tmp/bla
chown 1001 /tmp/bla
are both possible and provide the same result.
So for the trailing ":" case it should be (flexibly/convieniently) work
the same, no ?
