[PATCH 1/2] filter-branch: remove an unnecessary use of 'git read-tree'

[Johannes Sixt <j.sixt@viscovery.net>]

From: Johannes Sixt <j6t@kdbg.org>

The intent of this particular call to 'git read-tree' was to fill an
index. But in fact, it only allocated an empty index. Later in the
program, the index is filled anyway by calling read-tree with specific
commits, and considering that elsewhere the index is even removed (i.e.,
it is not relied upon that the index file exists), this first call of
read-tree is completely redundant.

Signed-off-by: Johannes Sixt <j6t@kdbg.org>

 Calling read-tree without arguments is not allowed according to the
 documentation. The next patch will enforce this.
