Is the web interface the _only_ way to interact with IMAP drafts on Gmail?
If that is the case, your patch (or Aaron's earlier attempt) to make the
document not to talk about imap-send in the context of Gmail makes sense.
No. An email client can sync with the drafts folder in GMail over
IMAP. However, sending the final email has to be done over SMTP.
The effect of "git imap-send" can be replicated by copy-pasting text
into the email client's compose interface. So, using "git imap-send"
seems like a bit of a roundabout way to me. There are some usecases
though (like queuing up patches as drafts before sending): so I'll add
a paragraph about this in my next revision.
