These lines were in the file when I started working with the port (more than 2 years ago ;), and although the definitions got moved around slightly, I never removed anything unless a problem was reported.  Now that we have this report, I propose removing BOTH of the S-tab lines.  I tried this locally and it did no harm, and let S-tab be interpreted (though some default mapping seems to translate it to plain tab).

The other stuff in ns-alternatives-map appears to be needed though, else the characters listed there don't get interpreted correctly.
