WAD. From the help:
--------------------
All of the TCC file handling commands that support ranges (for example, DIR, PDIR, TREE, COPY, MOVE, etc.) now support fuzzy filename matching using Levenshtein Distances if the filename begins with two asterisks (**filename). The Levenshtein Distance between two words is the minimum number of single-character edits (insertions, deletions or substitutions) required to change one word into the other.
--------------------
A leading "" never had a meaning in filename matches ( is used for subdirectory searches).
If you don't want to use the Levenshtein Distance wildcards, set LVSDistance=0 in your TCMD.INI.
