Another bug:

set -x
[ \( ! -e \) ] || echo $?
test \( ! -e \) || echo $?
test ! -e || echo $?
`command which test` \( ! -e \) || echo $?

gives:

+zsh:11> [ '(' ! -e ')' ']'
[: argument expected
+zsh:11> echo 1
1
+zsh:12> test '(' ! -e ')'
test: argument expected
+zsh:12> echo 1
1
+zsh:13> test ! -e
+zsh:13> echo 1
1
+zsh:1> which test
+zsh:14> /usr/bin/test '(' ! -e ')'
+zsh:14> echo 1
1

According to POSIX[*], this 4-argument test on ( ! -e ) is equivalent
to the 2-argument test on ! -e and this is valid (as you can see, the
"test" utility from the coreutils is correct). However, the current
versions of bash, dash and ksh93 under Debian are buggy too (even
worse, they return 2 for the first two tests).
