I'm sorry, I don't know where you learned to program Dscho, but
my mentors always taught me that user input should be handled
with care, and SIGSEGV / SIGBUS / SIGILL is not handling with
care!

We tell users to popuate the .git/info/grafts file.  By hand.
Its user input.  We shouldn't segfault over a malformed entry.
