added a rake plugin to disable zsh file globbing when calling rake tasks with square brackets

plugins/rake/rake.plugin.zsh

+alias rake="noglob rake" # allows square brackts for rake task invocation
+alias brake='noglob bundle exec rake' # execute the bundled rake gem
+alias srake='noglob sudo rake' # noglob must come before sudo
+alias sbrake='noglob sudo bundle exec rake' # altogether now ...
