TSQL queries over-enumerate dependent fields, at least in mkprof

[goodmami]

A TSQL query like i-id from result will enumerate the same i-id once for each time it corresponds to a line in the result file. I'm not sure this is itself a problem (consider if the query were i-id mrs from result), although it is different from what the LOGON/bin/tsdb utility does.

However, when a --where option is used with the mkprof command, this results in duplicate items. In this case, at least, the results should be made unique.
