And the apocs and exegs don't have line number anchors. Which leans things more towards having separate synop://, apoc://, and exeg://, except that such would just add more confusion to how to use the canonical "S03" abbreviations.

So nevermind that idea. We'll just support [aes://A01:121] under the assumption that as soon as someone starts using such it probably means that the particular apoc has been updated to have line-number anchors.

I haven't found the place yet where whitespaces are substituted by underscores :(

That would be the third line you quoted: (:

  $section =~ tr/ /_/;

I could have sworn that I'd seen other punctuation marks turned into underscores, leading to sometimes fairly long runs of underscores, but the code you quoted doesn't appear to do that. Sorry, I've got to get back to my day job or I'd look for examples to dis/prove that.

But, since nobody is complaining about "aes://" at this point, we can probably produce another patch (or, I hope, Corion will just update his).
