HEADS UP: doc/ slush begins for 11.0-RELEASE

[Marc Fonvieille]

Hello,

As announced, the doc tree is now in a slush.  Please postpone all
non-essential changes until after the doc tree is tagged (currently
scheduled for 8 July, 2016).

Please note that the slush does not apply to <lang>/htdocs documents.

While this is not a real freeze, if you need to commit a relatively
large change to fix or improve our documentation for 11.0-RELEASE,
please put a note for translators onto your commit log.
