While adding messages for a restyled login and create account forms I find they're getting longer and longer. E.g. the original field was named "yourpassword", and I'm distinguishing the two forms' fields, so userlogin-yourpassword. But when it comes to the placeholder text that appears in the input field, 'userlogin-yourpassword-placeholder' feels just too long (34 characters). I think as we start using HTML5 features and more fields get placeholders, it makes sense to use an abbreviation for that 11 character, so 'userlogin-yourpassword-ph' I explain this MessagesQqq.php, but how about mentioning abbreviations in <http://www.mediawiki.org/wiki/Manual:Coding_conventions#System_messages> ?
