every time you use a variable the last assigned value is used.
`include' in parse.y files is very, very similar to CPP' #include, so
in yuor example in the outer file you'll see the value defined in the
previously included file.  at least for me, it's expected behaviour.

-D is a "cheat mode" where you forcefully override variables in the
config.

to be fair i don't think i'll use variables or include files anytime
soon, just as i'm not using fancy `listen on': my setup is pretty
standard and could even work without a config file at all for the most
part.

However, I see some value in it.  It could help for example to have a
local config file while sync'inc the main gotwebd.conf across several
machines for example.  Most of the justification however is "because
vmd, smtpd, httpd, ... allow this."  I won't push for `include' if we
don't want it (at least initially) tho.
