- where n=nick, u=user, h=host, and d=domain
-
- With the following modifications: In the ``local'' portion of
- the hostname, all sequence of numbers are substituted with a
- single '*'. In the username, leading ~'s are also substituted
- with a single '*'.
-
- Returns:
- <address> in a wildcard mask according to <type>
-
- Examples:
- $mask(3 foo!bar@long.host.blah.com)
- returns:
- *!*bar@*.blah.com

- *!*@ppp-*-*-*-*.frobitz.com

-
- Other Notes:
- This function strips all tildes ('~') from the left of the username. For
- script writers, this means that in mask types 0 and 5, the function is
- *NOT* guaranteed to produce a mask matching the given address. If a script
- is to use these types, they should expect tildes to be stripped and be able
- to act accordingly.
