[patch] Do not run flyspell checks on org keywords

["Sébastien Delafond" <sdelafond@gmail.com>]

Here is a small patch that prevents flyspelle from checking all the Org
keywords. This is especially useful when using a dictionary other than
english.

Cheers,

Subject: [PATCH] [flyspell] Do not run flyspell-checks on {todo,all-time,additional-option-like}-keywords

  * this is useful when using flyspell with a non-English dictionary,
    or if some of your keywords are in another language
