+ The unalternates command can be used to write exceptions to alternates
+ patterns. If an address matches something in an alternates command,
+ but you nonetheless do not think it is from you, you can list a more
+ precise pattern under an unalternates command.
+
+ To remove a regular expression from the alternates list, use the
+ unalternates command with exactly the same \e[4mregexp\e[24m. Likewise, if the
+ \e[4mregexp\e[24m for a alternates command matches an entry on the unalternates
+ list, that unalternates entry will be removed. If the \e[4mregexp\e[24m for
+ unalternates is ``*'', \e[4mall\e[24m \e[4mentries\e[24m on alternates will be removed.
