allow multiple credential helpers for a single site

[peakschris]

Description of the feature request:

I have two different sets of credentials for two different subdirectories of a site:

my.site.com/sub1 <- credentials A
my.site.com/sub2 <- credentials B

the credential helper works great for specifying one set of credentials, but is specified not to consider the subdirectory in the scope.

I would like to be able to do this:

common --credential_helper=my.site.com/sub1=sub1_credentials.bat
common --credential_helper=my.site.com/sub2=sub2_credentials.bat

But I get:

ERROR: While parsing option --credential_helper=my.site.com/sub1=sub1_credentials.bat: Credential helper scope 'my.site.com/sub1' must be a valid domain name with an optional leading '*.' wildcard

Another option would be to follow docker's protocol, https://github.com/docker/docker-credential-helpers?tab=readme-ov-file#development; the URL is supplied to the credential helper, which can then return the appropriate auth.

the URL is supplied to the credential helper, which can then return the appropriate auth

This is already the case. The standard input to a credential helper is a JSON object with a uri key.

I missed this, thank you.
