Sounds like a good idea -- I've cc'd Jeff and Stefan (who
are the people who care for our git server)...

While being at it: seabios git url has changed, can the mirror be
updated please?  New URL is:

https://git.seabios.org/seabios.git

thanks,

Thanks, it is a good idea.  I think Peter also brought this up once before,
if I am not mistaken.  I'll work on implementing that today.

To check it is working correctly once configured, use the following:

  $ curl -si https://git.qemu.org/git/capstone.git/info/refs?service=git-upload-pack | grep --binary-files=text '^Content-Type'


Once configured correctly that should display:

   Content-Type: application/x-git-upload-pack-advertisement
