[PATCH v4 1/3] t: do not hide Git's exit code in tests

[larsxschneider@gmail.com]

From: Lars Schneider <larsxschneider@gmail.com>

Git should not be on the left-hand side of a pipe, because it hides the exit
code, and we want to make sure git does not fail.

There is one more occurrence of this pattern in t9010-svn-fe.sh which is to
evolved to change it easily.
