+       init.sh: avoid Solaris 10 /bin/sh portability problem
+       Solaris 10's /bin/sh does not pass '.' arguments 2.. to the
+       sourced script:
+         $ printf 'echo "$@"\n' > f; /bin/sh -c '. ./f bar'
+         $ printf 'echo "$@"\n' > f; /bin/bash -c '. ./f bar'
+         bar
+       tests/init.sh relied on that, accepting a --set-path=DIR argument,
+       and two tests used that idiom.
+       * tests/init.sh: Update suggested usage comments.
+       (path_prepend_): New function, to be used in place
+       of the --src-path=DIR option.
+       (setup_): Move PATH-prepending code into path_prepend_.
+       * tests/test-pread.sh: Adapt to new usage.
+       * tests/test-xalloc-die.sh: Likewise.
