Inappropriate Indentation for classes with keyword names

[nosewings]

Minimal example:

case class For()

On the line after this class declaration, pressing Tab causes an indentation. The same happens if I name the class If or While, but not, e.g., Foo.

On further inspection, I believe this is caused by the use of looking-at in scala-syntax:looking-back-token here, called from scala-indent:body-p here. M-x toggle-case-fold-search fixes the problem, so I'm not sure whether it should still be considered a bug.

Yes it's a bug. You shouldn't have to set anything. We need to add (let ((case-fold-search nil))) into all functions that use looking-at to fix this.

The best way would be to implement it once in scala-mode-lib.el (call it scala-lib:looking-at) and use that instead of the original.
