Subject: credential: use git_prompt instead of git_getpass
X-Git-Tag: v1.7.9-rc0~31^2~3
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=ce77aa4813c8a3980283c0a1e760f51f3a405154;p=git.git

credential: use git_prompt instead of git_getpass

We use git_getpass to retrieve the username and password
from the terminal. However, git_getpass will not echo the
username as the user types. We can fix this by using the
more generic git_prompt, which underlies git_getpass but
lets us specify an "echo" option.
