Using the same urlmatch_config_entry() infrastructure, add a new
mode "--get-urlmatch" to the "git config" command, to learn values
for the "virtual" two-level variables customized for the specific
URL.
git config [--<type>] --get-urlmatch <section>[.<key>] <url>
With <section>.<key> fully specified, the configuration data for
<section>.<urlpattern>.<key> for <urlpattern> that best matches the
given <url> is sought (and if not found, <section>.<key> is used)
and reported. For example, with this configuration:
[http]
sslVerify
[http "https://weak.example.com";]
cookieFile = /tmp/cookie.txt
sslVerify = false
You would get
$ git config --bool --get-urlmatch http.sslVerify https://good.example.com
true
$ git config --bool --get-urlmatch http.sslVerify https://weak.example.com
false
With only <section> specified, you can get a list of all variables
in the section with their values that apply to the given URL. E.g
$ git config --get-urlmatch http https://weak.example.com
http.cookiefile /tmp/cookie.txt
http.sslverify false
