 Replying to [comment:4 blair@…]:
 > Here's my new proposed patch which doesn't assume that ~/.sbtconfig sets
 SBT_JAVA_OPTS.  Let me know if this works for you.

 It works. But written in this way, shall we set JAVA_OPTS instead of
 SBT_JAVA_OPTS in ~/.sbtconfig then? This would make it more obvious,
 wouldn't it?
