Done Default initialization paths

[Steve Fabian]

Let TCMD and TCC search paths for .INI and TCSTART begin with the startup
directory (with possible exception of TCC on the right side of a pipe).
Under most circumstances the user specifies the startup directory. Another
special case that ought to be handled more automatically is when TCMD or TCC
is started from a removable device, esp. using the AUTORUN file.
