Probably because /bin/sh lacks basic POSIX functionality.

Tom, since the reexec lost all tracing, what about:

zsh -vx ./test-vc-list-files-cvs.sh

Jim, I'm wondering if init.sh should propagate v and/or x as part of the 
re-exec (certainly it would make it easier to get a full trace):

opts=
case $- in
  *v*) opts=v ;;
esac
case $- in
  *x*) opts=x$opts ;;
esac

"$re_shell_" -c$opts "$gl_shell_test_script_" 2>/dev/null

exec "$re_shell_" ${opts:+-$opts} "$0" --no-reexec "$@"

Hmm - I have bash 3.1.17 handy (not .16), but it passed for me on 
cygwin.  Tom, would you mind:

bash -cvx '
echo $BASH_VERSION
test $(echo y) = y || exit 1
test -z "$EXEEXT" && exit 9
shopt -s expand_aliases
alias a-b="echo zoo"
v=abx
     test ${v%x} = ab \
  && test ${v#a} = bx \
  && test $(a-b) = zoo \
  && exit 9
'

I'm assuming that $EXEEXT is empty on your setup, and bash 3.1 supports 
$(), so we shouldn't even be getting to the alias portion of the test.
