I'm not sure if people understand what this means. People might think "local wincred storage of credentials"? Maybe "wincred (for the current repository only)" and "wincred (for all repositores, activate in global config)".
Btw. what happens if a user executes "git config --global credential.helper wincred" and then "git config credential.helper wincred" (the entry is in local and global config)?
Btw. what happens if there is no local repository selected when the settings dialog is opened?
