man page with hint for brackets around ipv6 address

In the man page it sais nothing about the format you have to use if you want to copy from or to a host that is just an IPv6 address:

scp requires some special syntax as this example shows:

    $ scp filename user@\[fe80::203:6dff:fe00:83cf%eth0\]:/tmp/

The IPv6 address must be enclosed in brackets, which must then be escaped. If you’re logging in as a different user, the username goes outside the braces. And you must specify the local interface with the percent sign for Link Local addresses.

This should be added to the man page or as a hint in the error that occurs, if you try to use the command without brackets or without escape-signs, for example if there are several colons in the hostname, instead of for example

    $ scp -6 user@2001:db8:0:1:/tmp/test.file .

    > ssh: Could not resolve hostname 2001: Address family for hostname not supported

it should say something like

    > ssh: missing brackets around IPv6 address
