I am not 100% sympathetic if ../torvalds/linux-2.6.git/ was what caused
this.  Perhaps 30% or so ;-).

However, I think /pub/scm/linux/kernel/git/torvalds/linux-2.6.git/ would
result in the same breakage, and that is something I consider gravely
broken.

If both are fixed by rethinking the make_absolute_path(), that would be
good.
