Maddening. There's an ancient wishlist bug to allow # comment lines. There's even a very simple patch. There's no response from a maintainer. (There was a retitle action, but AFAIK, Thomas Hood wasn't a maintainer at that time).
What's the holdup? Where's the fuckin' problem? Yeah, yeah, we don't have time. Time to apply one very simple patch? For something that should have been there right from the start?
Oh, I do see a reason for not applying the patch: there's an "Explanation" tag you can use. The apt guys don't come out and say it, but that's what they think. I'm pretty sure of that, judging by what I read of Adam Heath over the years.
But not responding to that report at all is... cowardice.
(Oooh, some people will hate me for that, or alternatively think I'm an idiot. I'm used to the latter...)
