Overview

Collapses the parts of a message that vary between occurrences of the same bug.

Error backends typically fingerprint on the message (Solid Errors hashes exception class + message + severity + source), so an id, a URL or a digest inside the text would split one recurring bug into an unbounded number of groups. Normalising first keeps one bug to one row.
