[PATCH v3 1/4] imap-send: return with error if curl failed

From: Nicolas Morey-Chaisemartin <hidden>
Date: 2017-08-22 15:56:23

curl_append_msgs_to_imap always returned 0, whether curl failed or not.
Return a proper status so git imap-send will exit with an error code
if womething wrong happened.

[PATCH v3 3/4] imap_send: setup_curl: retreive credentials if not set in config file

From: Nicolas Morey-Chaisemartin <hidden>
Date: 2017-08-22 15:56:34

Up to this point, the curl mode only supported getting the username
and password from the gitconfig file while the legacy mode could also
fetch them using the credential API.

[PATCH v3 4/4] imap-send: use curl by default

From: Nicolas Morey-Chaisemartin <hidden>
Date: 2017-08-22 16:02:55

Now that curl is enable by default, use the curl implementation
for imap too.
The goal is to validate feature parity between the legacy and
the curl implementation, deprecate thee legacy implementation
later on and in the long term, hopefully drop it altogether.
