[PATCH] t7004: do not chdir around in the main process

[PATCH] t7004: do not chdir around in the main process

[Junio C Hamano]

From 11f438cea119c52cc0c982f2b859defb37fd8c64 Mon Sep 17 00:00:00 2001
Move down to no-contains subdirectory inside a subshell, just like
the previous step that created and used it does.

Signed-off-by: Junio C Hamano <gitster@pobox.com>

 * I noticed this while writing the --sort=version:tag test and
   failing to find the test vector files I was creating in the test.
   It turns out that the files I expected was inside a subdirectory
   because this test piece chdir'ed down and nobody came back up
   from there.
