Nasty.  With NO_BAD_PATTERN, exec.c around line 1177 is repeatedly
globbing the same line because it is always returned containing
tokens.  Any problem with the having NOBADPATTERN untokenize at that
point?  As globbing is the last operation, I can't see any.

The non-interruptibility is a different bug, but that's now traditional.
