+       init.sh: fix an error in the previous change; add more comments
+       * tests/init.sh: Compare exit code in loop against 9, not 2.
+       Patch by Bruno Haible.
+       Make the two tests more similar by adding an empty "then" clause.
+       Add comments.
+
+       init.sh: avoid unnecessary shell re-exec
+       * tests/init.sh: Improve the re-exec-required check to first test the
+       current shell.  If it passes the test, do not search for a shell that
+       does pass, and do not re-exec.  This test is particularly contorted to
+       avoid triggering misbehavior in Solaris 10's /bin/sh whereby any use
+       of $(...) evokes a syntax error and causes immediate shell exit with
+       status 2.  Bruno Haible reported that the re-exec made it impossible
+       to single-step through any init.sh-using script.
