The /bin/sh distributed with 4.nBSD (for n <= 4, at least) is a really
old, buggy, puny version of the Bourne shell.  I was going to supply a
modern version for 4.3BSD but Berkeley balked at requiring a UNIX
System V source license of their "customers".  The current edition of
the BRL SVR2 shell can be easily configured to replace a 4BSD /bin/sh.
(Info about this was posted not long ago, so I won't repeat it here.)
