Comment (by boklm):

 I uploaded a new version of the patch in branch bug14959-v2:
 https://gitweb.torproject.org/user/boklm/tor-browser-
 bundle.git/commit/?h=bug14959-v2

 Now if the shasum doesn't match, we use "signmar -r" to remove the
 signature on the MAR file and check the shasum again. So it should work
 for both signed and unsigned MARs (the unsigned case might be useful for
 the generation of 4.0 -> 4.5 incrementals).

 To test this on 4.5a4, I had to uncomment the lines checking the gpg
 signature of the sha256sums.txt file, as the signature on 4.5a4 is wrong
 at the moment.
