I am new to zsh and I like it a lot, especially with oh-my-zsh plugin. I installed oh-my-zsh with its default values and can't figure out how to turn off autocompletion for specific commands, that I often use, such as:
sudo mc or sudo gem update. The thing is that I have .mc directory and .gem directory and zsh proposes corresponding autocompletions (for .mc and .gem).
Generally I would like to config zsh so that sudo is not considered a separate command (which it is not) with the following as a params. Is there a config for that?
