TPIPE, crash and question

I'm using v21. v20 also has these problems.

1. Interrupting this command with Ctrl-C causes "TPIPE.EXE has stopped working" (details below). The file in question can be obtained here:
copy "" delegated-arin-latest
tpipe /input=delegated-arin-latest /replace=0,0,0,0,0,0,0,0,0,"|"," "
Problem signature:
Problem Event Name: APPCRASH
Application Name: TPIPE.EXE
Application Version:
Application Timestamp: 58fea558
Fault Module Name: KERNELBASE.dll
Fault Module Version: 6.1.7601.17932
Fault Module Timestamp: 503275ba
Exception Code: 0eedfade
Exception Offset: 0000d3cf
OS Version: 6.1.7601.
Locale ID: 1033
2. The help says I can use wildcards with TPIPE's /input, but
v:\ipreg> tpipe /input=delegated-*-latest /replace=0,0,0,0,0,0,0,0,0,"|"," "
TPIPE: The filename, directory name, or volume label syntax is incorrect.
