... and I end up in /bin/sh also - I checked; there is no file "+"
anywhere on my file system, but if there is a file (regardless of
contents!) anywhere on the path, typing "+" does produce a /bin/sh !
Can anyone explain this, please? This is on SCO Xenix System V r 2
version 2.2.1; Approximately SysVr2, with Berkeley-isms (like having
a csh).
