[PATCH v10 01/10] t7600: clean up style

[Phillip Wood <phillip.wood123@gmail.com>]

From: Denton Liu <liu.denton@gmail.com>

Clean up the 'merge --squash c3 with c7' test by removing some
unnecessary braces and removing a pipe.

Also, generally cleanup style by unindenting a here-doc, removing stray
spaces after a redirection operator and allowing sed to open its own
input instead of redirecting input from the shell.
