It is possible to do in this way, but it less efficient, because it uses
index_pipe, which does not know the actual size, so it reallocates the buffer
as it reads data from the descriptor, while index_fd uses xmap() instead.
So I sent another solution yesterday:
http://article.gmane.org/gmane.comp.version-control.git/90968

It is a bit hackish because I unset S_IFREG bit in st_mode to disable
conversion. In fact, my question what would be a better way to tell index_fd
to not do any conversion. If you think that it is better to use index_pipe,
which does not any conversion than I will redo my patch to use it instead.
