[SVN] svn diff problems

[Allan Odgaard]

Actually, the diff with HEAD/BASE/PREV is broken (starting with rev.  
1145) for me because I do not set up TM_SVN (or PATH for that  
matter), have svn in /opt/local/bin and since these 3 diffs are now  
commands with Ruby as interpreter, the normal PATH setup done by  
running bash_init.sh is not done (since bash is not involved when  
specifying interpreter).

Since I'd prefer to have this working w/o the need for setting up  
variables, I suggest we call ruby from bash instead of setting it as  
interpreter for these three commands, unless there's a better solution.
