`combined-vhost` format doesn't support ports in the vhost

[mjsir911]

lines like this:

m.wizard.gay:443:71.6.134.234 - - [29/Oct/2025:00:20:59 +0000] "GET / HTTP/1.1" 200 4686 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/133.0.0.0 Safari/537.36"

don't work because it's interpreting the port after the ip address as the ip address:

{Path: "/", Title: "", Event: false, Ref: "", Size: "", Query: "", Bot: 0, UserAgent: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/133.0.0.0 Safari/537.36", Location: "", IP: "443", CreatedAt: "2025-10-29 00:20:59 +0000 UTC", Session: "", Host: "m.wizard.gay"}

this is probably a lil bit related to #840

I don't think there's a backwards-incompatible fix to this other than not log the ports in the output format, which might be reasonable but this + #840 really feels like there should just be some documented log formats to use with nginx (or apache, or whatever)

for a little bit of context, here's someone being confused about similar-ish things but standard convention for vhost_combined seems to be delimiting the vhost by a space and not a colon:

• https://blog.neilsabol.site/post/goaccess-apache-httpd-logformat-log-format-combined-common-vhost/

and examples of this kind of non-standard standard being used:

• https://httpd.apache.org/docs/current/mod/mod_log_config.html#:~:text=NCSA%20extended
• https://github.com/allinurl/goaccess/blob/4ab37d5360f9796be0a0491bc5644f48fdee3ff2/src/settings.c#L71

• unsure of any other examples?
