[PATCH v9 04/11] t7502: clean up style

[Denton Liu <liu.denton@gmail.com>]

Refactor out Git commands that were upstream of a pipe. Remove spaces
after "> ". Indent here-docs appropriately. Convert echo chains to use
the test_write_lines function. Refactor 'sign off' test to use test_cmp
instead of comparing variables.
