Currently, do_push() in push.c calls remote_get(), which gets the configured remote for fetching and pushing. Replace this call with a call to pushremote_get() instead, a new function that will return the remote configured specifically for pushing. This function tries to work with the string pushremote_name, before falling back to the codepath of remote_get(). This patch has no visible impact, but serves to enable future patches to introduce configuration variables to set pushremote_name. For example, you can now do the following in handle_config(): if (!strcmp(key, "remote.pushdefault")) git_config_string(&pushremote_name, key, value); Then, pushes will automatically go to the remote specified by remote.pushdefault.
