 From the r1431 release notes:

     [NEW] TextMate sets TM_FULLNAME (unless you set it yourself)
     to the user’s full name, so no longer necessarily to fiddle
     with niutil and dscl to obtain it.

So it should not be necessary for commands/snippets to try and obtain  
the full username themselves.
