I wonder if Git::credential (or even the underlying lower level
credential_fill() in the helper API) should give hints to the caller
if calling it again may yield a different result. An interactive
prompt may allow the user to mistype the password and then a later
call may return a correct one, but the .netrc helper will read from
the file and will return a fixed result, so there is no use calling
credential_fill() again. And in the latter case, you do not want to
loop $askpasswordcount times.
I also have to wonder if this logic belongs to git-send-email.
Specifically, I wonder if we can place the looping logic in
Git::credential, so that other users of the library can take
advantage of it?
Thanks.
