That much was true. What the commit message didn't explain, but which a careful review of the code might have noticed as odd, was that the revised regex started with `^[^\a]`—matching strings that didn't start with [the ASCII bell character 0x07](https://en.wikipedia.org/wiki/Bell_character). The bell character was a historical artifact from the early days of computing. No sane request would start with a bell, and so the odd start to the regex would do no harm ... unless, perhaps, some client _were_ to start their request with a bell character, in which case the regex would fail to match and the request would silently fail to be logged.
