PATCH: avoid hashing command names twice on Cygwin

["Andrej Borsenkow" <Andrej.Borsenkow@mow.siemens.ru>]

Under Cygwin every foo.exe was hashed twice - as foo and foo.exe.

Actually, the code was funny. It contained one block that was executed
unconditionally and exactly the same later under condition.

Have a nice DOS!
