I was looking how to properly set up hunk-headers for C# and found
a mail from Adam Petaccia to this list, that almost did what I wanted.
It was never included, so I improved it and I hope it can be added
to the official repository now.

Can you also add a line in Documentation/gitattributes.txt so that
people know your pattern is there? In the "custom hunk-header"
section, there is already a list to add to.

Thanks. I ran a few diffs on what little C# code I have, and it did seem
to be an improvement. So:
