07cond test failure

Test 07cond.ztst failed: bad status 1, expected 0 from:
  [[ -g modish && ! -g zerolength ]]
Was testing: -g cond

SUS V2 specifies this as implementation dependent.

Why 07cond sets umask to 077?

Hmm ... I'm afarid I was not clear enough. 07cond.ztst sets umask to 077 and
creates directory modish that gets permissions 700. Than it tries to set
SGID bit that fails because x bit is not set for group and SGID is not
permitted in this case.

You were clear enough.

It's so the files are guaranteed not to have any modes that zsh does
not actually set, I think.  Here's a simple patch; it should work, but
let me know anyway:
