Subject: connect: change verbose IPv6 address:port to [address]:port
X-Git-Tag: curl-7_86_0~128
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=2b309560c1e5d6ed5c0e542e6fdffa968b0521c9;p=thirdparty%2Fcurl.git

connect: change verbose IPv6 address:port to [address]:port

- Use brackets for the IPv6 address shown in verbose message when the
  format is address:port so that it is less confusing.

Before: Trying 2606:4700:4700::1111:443...
After: Trying [2606:4700:4700::1111]:443...

Bug: https://curl.se/mail/archive-2022-02/0041.html
Reported-by: David Hu

Closes #9635
