Fix style problems such as unnecessary use of quotes, add helper variables to reduce visual clutter, and other minor fixes to make the first batch of tests more closely resemble the second round tests. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com>

# FS QA Test No. 229
|
|
#
|
|
# See what happens if we CoW blocks 2-4 of a page's worth of blocks when the
|
|
# surrounding blocks vary between unwritten/regular/delalloc/hole.
|
|
#
|
|
# This test is dependent on the system page size, so we cannot use md5 in
|
|
# the golden output; we can only compare to a check file.
