Subject: t: use test_seq -f and pipes in a few more places
X-Git-Tag: v2.54.0-rc0~148^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0678e01f0211f4e3310f3c01b3425da53aa63677;p=thirdparty%2Fgit.git

t: use test_seq -f and pipes in a few more places

Several tests use a pattern that writes to a temporary file like this:

  printf "do something with %d\n" $(test_seq <count>) >tmpfile &&
  git do-something --stdin <tmpfile

Other tests use test_seq's -f parameter, but still write to a temporary file:

  test_seq -f "do something with %d" <count> >input &&
  git do-something --stdin <input

Simplify both of these patterns to

  test_seq -f "do something with %d" <count> |
  git do-something --stdin
