Do not store wrong credentials in Keychain

[sorin-ionescu]

If I type the user name and/or password wrong, it stores said wrong credentials in the Keychain and attempts to use them for each subsequent command. I have to manually edit the entry in Keychain to fix it.

Yes, this is something I had encountered while writing the program. I am not sure if there is a way to solve this because the only thing that git sends to program is "Username: " or "Password: " and doesn't notify it later if the username/password worked.
