DoEnd too aggressive.

[aarontharris]

When pseudoing, it is common for me to have actions such as: doThisThing().
Yet when I type "do" it automatically adds "end" which I do not use and must then delete.

Suggestion, instead of auto-adding the "end" upon the "o" keystroke of "do". Perhaps a whitespace character such as [space] or [enter] following "do" can trigger the addition of "end" ?

Alternatively (if it is easier) maybe just a config-option to allow us to disable the do-end autocomplete for those of us that do not use it.

Thanks in advance, I really like the plugin!
