I think that assert can be reenabled now.

Reenabled the assert.

Do we need to do anything for columns? Either way a test would be welcome.

From what I've seen the columns are correct. I will add a test for that.

In the previous version of the compiler bridge we were adding 1 here:
https://github.com/sbt/zinc/blob/fc58a39402ca7abfda17133a5b3a43de3344ca49/internal/compiler-bridge/src/main/scala/xsbt/DelegatingReporter.scala#L99
which means Zinc expects line numbers starting at 1, while in Dotty we provided it with ones starting at 0.
This wasn't an issue when using dotc and sbt, since dotc added 1 to show the correct line number and sbt most likely used the Dotty rendered message due to:
https://github.com/sbt/zinc/pull/699/files?diff=unified&w=1
This popped up when adding some test in Bloop: tgodzik/bloop#1
Let me know if we should fix it differently. This is needed for the work I am doing on the Metals/Dotty integration.
