The credentials configuration values already support url-specific
configuration items in the form credential.<url>.*. This patch
adds similar support for http configuration values.
The <url> value is considered a match to a url if the <url> value
is either an exact match or a prefix of the url which ends on a
path component boundary ('/'). So "https://example.com/test"; will
match "https://example.com/test"; and "https://example.com/test/too";
but not "https://example.com/testextra";.
Longer matches take precedence over shorter matches with
environment variable settings taking precedence over all.
With this configuration:
[http]
useragent = other-agent
noEPSV = true
[http "https://example.com";]
useragent = example-agent
sslVerify = false
[http "https://example.com/path";]
useragent = path-agent
The "https://other.example.com/"; url will have useragent
"other-agent" and sslVerify will be on.
The "https://example.com/"; url will have useragent
"example-agent" and sslVerify will be off.
The "https://example.com/path/sub"; url will have useragent
"path-agent" and sslVerify will be off.
All three of the examples will have noEPSV enabled.

+http.<url>.*::
+ Any of the http.* options above can be applied selectively to some urls.
+ For example "http.https://example.com.useragent"; would set the user
+ agent only for https connections to example.com. The <url> value
+ matches a url if it is an exact match or a prefix of the url matching
+ at a "/" boundary. Longer <url> matches take precedence over shorter
+ ones with the environment variable settings taking precedence over all.
+ Note that <url> must match the url passed to git exactly (other than
+ possibly being a prefix). This means any user, password and/or port
+ setting that appears in a url as well as any %XX escapes that are
+ present must also appear in <url> to have a successful match. The urls
+ that are matched against are those given directly to git commands. In
+ other words, use exactly the same url that was passed to git (possibly
+ shortened) for the <url> value of the config setting.
