======Synopsis:======
[[on]] [<modes>]unknown_command [<serial#>] [-|^]<match> { <action> }

======Description:======
Whenever the command in a [[command statement|ircii_syntax]] is neither
a builtin command nor a user-created alias, it is an //unknown command//.
When [[set unknown_command]] is **off**, the command statement is hooked
through this handler.

This feature is intended for automatic command completion.  If the command
statement explicitly prefixed the command with two slashes, indiciating a
built-in command, then those slashes will be preserved.  In all other cases,
any leading slashes will be omitted.

======Parameters:======
|$0    |The unknown command in a command statement |
|$1-   |The arguments to the unknown command       |

======History:======
