Blame bentley for that. I think he originally wrote the man pages, and I 
think they provide good defaults that are more convenient than directly 
messing with groff formatting, so I use it for all my (admittedly few) 
man pages.

It does make sense, and I do run this from time to time. The warnings 
haven't been fixed mainly because they seemed harmless/false positives, 
but this seems like a good occasion to discuss them, if you want.

My understanding is that the Xr order is supposed to be by section, then 
alphabetical, right?
The rationale for our ordering is that it is the order in which we 
expect the users to read the manual pages; this made more sense back 
when we served the renders online directly; now that we have a separate 
navbar, it might be okay to reorder the footers.

I haven't found any thus far, but my testing isn't thorough. We haven't 
really set up any kind of anchor checker, sadly.

Again, blame bentley. I didn't realise this page existed until I went 
through two fairly small links lost in the middle of others. Good 
resources, despite not being very easy to find. I'll fix this.
(I'm also noticing the '\-', and I /really/ hope we didn't mess up and 
use a breakable hyphen in places we shouldn't have...)

Great! That said, I'm reluctant to use a non-release version of Mandoc 
in our documentation generator, as I don't have much time to dedicate to 
maintaining it; so I think I'll patiently wait for the next release.

Late but yours nonetheless,
