[nongnu] elpa/scala-mode aebed53 168/217: Mark a couple of indentation variables as safe (#105)

[ELPA Syncer]

branch: elpa/scala-mode
commit aebed53225599cad6243a0d162089c1fceb5a676
Author: Sebastian Wiesner <swiesner@lunaryorn.com>
Commit: Sam Halliday <sam.halliday@gmail.com>

    Mark a couple of indentation variables as safe (#105)
    
    These variables can reasonably set with `.dir-locals.el`.  Marking them as 
`:safe` removes the nagging prompt when doing so.
