[PATCH] Improve git bisect error message

[PATCH] Improve git bisect error message

[Andi Kleen]

It took me some time to figure out what this error message meant and
how to fix the problem.  So let's improve it a little.

It is very much appreciated that you report a problem and moreover provide a 
patch.

Unfortunately in this case it seems that your git version is too old and the 
problem may have been fixed in newer versions.

See:

So I think you should upgrade to git 1.5.5.1 and if possible tell us if you 
still get the same error message. 

Thanks,
Christian.
