I think that this makes two changes:
1. expands x\{1,\} to xx*.
2. writes x\{,1\} more explicitly as x\{0,1\}.
I see that POSIX does not allow x\{,1\} (I had not realized that
before), so change #2 one makes sense to me. But POSIX says that
\{m,\} is allowed, so I don't see why change #1 is necessary. Does
NetBSD not implement \{m,\}?
Thanks,
Ben.
