Comment #5 on issue 1166 by pekka.klarck: New `@{EMPTY}` variable
http://code.google.com/p/robotframework/issues/detail?id=1166
This issue was updated by revision 38db05920aa1.

I moved the documentation of @{EMPTY} to separate paragraph from ${EMPTY}  
and ${SPACE}. Also added a bit better example and a note about this  
variable being added in 2.7.4.

Ilmari, please review the changes and close this issue if you are happy  
with them.
