If we are doing this modernization to use write_script more, we probably should make "expect" and "actual" text files that end with a complete line. I.e. -- >8 -- Subject: t1020: do not overuse printf and use write_script The test prepares a sample file "dir/two" with a single incomplete line in it with "printf", and also prepares a small helper script "diff" to create a file with a single incomplete line in it, again with "printf". The output from the latter is compared with an expected output, again prepared with "printf" hance lacking the final LF. There is no reason for this test to be using files with an incomplete line at the end, and these look more like a mistake of not using printf "%s\n" "string to be written" and using printf "string to be written" Depending on what would be in $GIT_PREFIX, using the latter form could be a bug waiting to happen. Correct them. Also, the test uses hardcoded #!/bin/sh to create a small helper script. For a small task like what the generated script does, it does not matter too much in that what appears as /bin/sh would not be _so_ broken, but while we are at it, use write_script instead, which happens to make the result easier to read by reducing need of one level of quoting.
