Subject: Add class to EditPage text area when editing an old revision
X-Git-Tag: 1.31.0-rc.0~5030
X-Git-Url: http://git.cyclocoop.org/%7B%24admin_url%7Dcompta/comptes/journal.php?a=commitdiff_plain;h=81698d4c1605f491709e636acd5ca0e6857e3821;p=lhc%2Fweb%2Fwiklou.git

Add class to EditPage text area when editing an old revision

This adds a class 'mw-textarea-oldrev' to the editing area when an old
page revision is edited. It seems that the warning MediaWiki:Editingold
is not sufficient for some users and some css tweaks might be
appreciated, as is already done for protected pages.
