On most shells `:>file || framework_failure_` will not evaluate the framework_failure_ even if there was an error writing the file. shells which do evaluate the failure are ksh 93u+ and bash 4.2, while shells wich don't include bash 4.3, solaris, freebsd, dash. Furthermore this construct is problematic on Solaris 10 sh, which will try to optimize away a `:' command in a loop after the first iteration, even if it is redirected. * tests/cp/link-deref.sh: Remove the leading colon on redirections. * tests/cp/reflink-perm.sh: Likewise. * tests/id/zero.sh: Likewise. * tests/install/install-C.sh: Likewise. * tests/misc/env.sh: Likewise. * tests/misc/md5sum-bsd.sh: Likewise. * tests/misc/runcon-no-reorder.sh: Likewise. * tests/mv/partition-perm.sh: Likewise. * tests/rm/r-root.sh: Likewise. * tests/split/l-chunk.sh: Likewise. * tests/split/line-bytes.sh: Likewise. * tests/tail-2/inotify-rotate.sh: Likewise. * tests/tail-2/retry.sh: Likewise. * tests/tail-2/symlink.sh: Likewise. * tests/tail-2/wait.sh: Likewise. * tests/touch/read-only.sh: Likewise. + cfg.mk (sc_prohibit_colon_redirection): A new syntax check to avoid further instances of this creeping in.
