[PATCH] Git.pm: release hash and blob handles

[Ray Chuan]

the methods

 * hash_and_insert_object
 * cat_blob

use bidirectional pipes to pull/push data from the various git
utilities, but they don't close them after this is complete. this
denies Git's subsequent attempts to use these resources, leading to
failure.

a simple, reproducible test case can be seen at

Hmm, I don't understand why git-svn does not work for you, but this
patch is not correct. The whole point of the infrastructure is to leave
the pipes open so that subsequent calls _reuse_ these pipes. This leads
to substantial speedup as you do not need to re-fork git all the time.
