Some remarks below, not supposed to sound whiny, just want to
understand where certain things are specified and if there might be
some need to improve documentation to make it easier for contributors.
It's not that amusing to spend a substantial amount of time on
formatting your code in a coding standard you're not familiar with just
to hear that it's completely wrong. Ultimately I'm aiming to provide
patches that conform to the project's style expectations.

http.c makes heavy use of initialization in declarations (which I'm a
big fan of), but which is discouraged by style(9) ("Be careful to not
obfuscate the code by initializing variables in the declarations."). I
spent some time removing those from my code (even though I thought it
looks better with them), so maybe it's not as strict as I thought it
is - ultimately "obfuscate" is kind of a subjective term?

Hm, I used an emacs mode that was supposed to indent according to
style(9) - so maybe that wasn't the right tool. Do you have a link to
an emacs mode that works like expected? (I clearly won't do these
indentations manually, they're so counter-intuitive to me that I
would mess them up badly - it's hard to work against your organization's
usual coding style and switching back and forth). Any recommended
combination of lint/indent/whatever I could use to validate the code

I just checked, all lines I added are <80 characters. Style(9) itself
doesn't specify any line length limitations, so I figured staying below
80 is already quite conservative (or are you going really old school
and limit yourself to 72?). Since I found quite a number of lines
that are longer than that I figured it would be ok.

Thought I caught them all ;) I clearly forgot about "for" loops -
force of habit, sorry.

I wasn't aware that this is not allowed (it's such an incredibly
useful feature to me). Could you point me to the section in style(9)
that specifies this (couldn't find it)? In regards of declaration sort
order in style(9) I read up on it and understand now what's expected.

Do you have a good pointer to style guides for man pages/nroff? Didn't
bump the date since I figured it won't be accepted unchanged anyway.
