[dcl.attr.grammar]/6 ill formed and malformed are poorly formed

[sdutoit]

From an email to cxxeditor@:

§7.6.1/6
In the note there is "ill" and "formed" on separate lines but the - is missing in between.

The example uses term "malformed" even though the note uses ill-formed. Also malformed
is not used anywhere else in the standard.
