[request-tracker-maintainers] Bug#597496: Now in upstream git for 3.8

[Dominic Hargreaves]

<https://github.com/bestpractical/rt/commit/8105bc6c556e429915a2e566bfaa7661891e2115>

Since this is a small isolated change in a new piece of code, and I'm
preparing another update for an RC bug, I will ask the release team
whether we could include this.
