I'll look into that. We actually had some discussion about this on IRC
and I was thinking of taking this feature to a new level... something
like:
- by default we show names as they come in (least surprise)
- we offer to reverse Last, First
- we offer to shorten to FirstL
- we offer an alias map
So I could define that mail from "cworth at cworth.org" gets the author
listed as "cworth". Or as CarlW.

Happy to comply to your preferences in the future

Ok, I'll try to be more explicit in documenting algorithms

Nope. Will do.

Oops.
