Dot is deprecated by POSIX. But chown still supports dot as well as
colon. Here's an excerpt from the chown info page.
Some older scripts may still use `.' in place of the `:'
separator. POSIX 1003.1-2001 (*note Standards conformance::) does
not require support for that, but for backward compatibility GNU
`chown' supports `.' so long as no ambiguity results. New scripts
should avoid the use of `.' because it is not portable, and
because it has undesirable results if the entire OWNER`.'GROUP
happens to identify a user whose name contains `.'.
Similarly, in the ssh port-forwarding arguments
ssh -L 80:localhost:80 ...
colon is deprecated in favor of slash. Colon is a component
of IPv6 addresses.
ssh -L 80/::1/80 ...
