Source files in the project root directory are not fixed

[olafurpg]

A project like this

Foobar.scala
build.sbt

will compile Foobar.scala (it's in sources) but scalafix won't fix it since the root directory is part of unmanagedSourceDirectories. I'm not sure which sbt setting is appropriate to use here besides sources. I prefer to avoid sources since that includes managed sources (code generated) which is pretty meaningless to fix. I might make sense to read sources in scalafix instead of unmanagedSourceDirectories by default.

Question is, should scalafix consider *.scala files in the baseDirectory?

It seems we can use

> help sourcesInBase
If true, sources from the project's base directory are included as main sources.

to decide whether to include *.scala files in the base directory.
