Synopsis:
   $igmask(<mask>)

Technical:
   Scriptable interface to the list of users on the ignore(1) list.

Practical:
   This function would be ideal in a script that redefines the ignore(1)
   command. The script could display the list of ignores, or even tell the
   user if they're ignoring the same user twice.

Returns:
   space separated list of entries in the ignore list matching <mask>

Examples:
   /ignore foo!bar@test.org ALL
   /ignore nobody!fnord@more.nothing.com MSGS

   /eval echo $igmask(*foo*)
     FOO!BAR@TEST.ORG
   
   /eval echo $igmask(*)
     FOO!BAR@TEST.ORG NOBODY!FNORD@MORE.NOTHING.COM
