[Question] get_maintainer:

[Manuel Ebner]

I'm preparing a patch for get_maintainer. While testing I found out that
the order of the output can change for the same input - see below. That's
without any change to get_maintainer.pl. (state of 09d8b39563e84fc245 ).
It seems that the alternating execution of get_maintainer and
get_maintainer_patched triggers the glitch. Even if both files are the same.
I can't figure out what's the root cause. I think I change the state of the
script or it's surroundings somehow, but I can't figure out where.

Any Ideas?

Thanks
 Manuel
