Subject: * lib/irb/locale.rb (IRB::Locale#search_file): make it possible   to
 load a localization from a gem.   (IRB::Locale#lc_path): obsoleted because of
 the change of #search_file   (IRB::Locale#each_localized_path): new private
 method, based on lc_path   (IRB::Locale#find): follows the change of
 #search_file.   (IRB::Locale#load): removed duplicate with #find.
