I was just working on a reply to my own email as I realized it was
only  dumb-luck that converted 1200 noisy changes into a couple of
dozen.  "-S" matches only  the string itself, not the line the string
resides on.  So, -Sxyz will match if  "xyz" itself was added or
deleted in the diff (if "xyz" is on a line that's changed but  did not
itself change, it won't match).  Funny that I actually knew this -- I
use it to look for System.out.println additions among other things.

Yes (though I couldn't have told you that without experimenting -- I
always assumed it checked whole lines).

The -Sstring counts the number of 'string' in preimage and postimage and
skips the commit if they are the same.  Nothing more.
