I found that pacman was triggerin the progressbar callback twice when pointing to my repo, which uses Mirrorbrain to geolocate the closest mirror. After asking here in this list and in the curl library list, the thing was that my header redirection response had a body, so curl was triggering twice, downloading first just bytes (of the redirection) and then the proper file. I changed the dload.c code to avoid this, I don't know if it is correct to do it the way I did. Now is triggering just once.
Shorten that a bit and it would be a perfect commit comment. It should explain the reasoning behind the change and a way to reproduce the original problem. If people want to read the whole story there is an ML archive. Maybe something like this:
Redirections with a body (e.g. mirrorbrain) should trigger the progress bar only for the package download. Without this patch you get two bars (redirection and download).
You can also be more precise in the subject (which is probably more important than the body): "Hide download progress bar for redirection with body"

Please use git send-email[1] in the future. Most other clients will mangle indentation and/or line breaks for long lines. Also please read HACKING (in the top level of the git repo). "if" should be followed by the brace without a space in between. [1]: https://wiki.archlinux.org/index.php/Super_Quick_Git_Guide#Sending_patches
