The last test fails because of an unexpected exit code?

POSIX says (http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_08_02):
If a command is not found, the exit status shall be 127. If the
command name is found, but it is not an executable utility, the exit
status shall be 126.
Andreas.

That sounds like a bit of a grey area -- is ENAMETOOLONG nearer to
ENOENT or EACCES? Maybe it's best to make the test allow either (given
that it's not a test of shell behaviour).
I can update the test to do that, but it probably won't be until the new
year I'm afraid.
