GIT/SSH_ASKPASS used for username input in https:// URLs

Hi everyone,

there is an interesting wart around prompt.c - PROMPT_ECHO isn't used in invoking an external helper program.

Thus, if I clone something on https (which requires auth for that), and have SSH_ASKPASS set, I will get two GUI *password* prompts, even though the first one will indicate in the title that it *is* asking for the username.

But basically, given the trivial protocol of SSH_ASKPASS, there doesn't seem to be any way to properly fix this without support from any desktop environment that sets SSH_ASKPASS. :-(

The best I can currently tell my users is to use the
   [credentials "https:/..."]
configuration to fix the username.

But if we can't fix this, maybe we can at least point this out in the docs?
