Calculates the set of unambiguous abbreviations for the strings in `self`.

    require 'abbrev'
    %w{ car cone }.abbrev
    #=> {"car"=>"car", "ca"=>"car", "cone"=>"cone", "con"=>"cone", "co"=>"cone"}

The optional `pattern` parameter is a pattern or a string. Only input strings that match the pattern or start with the string are included in the output hash.

    %w{ fast boat day }.abbrev(/^.a/)
    #=> {"fast"=>"fast", "fas"=>"fast", "fa"=>"fast", "day"=>"day", "da"=>"day"}

    Abbrev.abbrev(%w{car box cone}, "ca")
    #=> {"car"=>"car", "ca"=>"car"}
