httppeer: calculate total expected bytes correctly User-facing error messages that handled httplib.IncompleteRead errors in Mercurial used to look like this: abort: HTTP request error (incomplete response; expected 3 bytes got 1) But the errors that are being handled underneath the UI look like this: IncompleteRead(1 bytes read, 3 more expected) I.e. the error actually counts total number of expected bytes minus bytes already received. Before, users could see weird messages like "expected 10 bytes got 10", while in reality httplib expected 10 _more_ bytes (20 in total).
