Yes, they are different: linkToolbarHandler.js has a newline
just before EOF, whereas linkToolbarHandler.js.bak lacks one.

It works for me:

   $ diff -u linkToolbarHandler.js.bak linkToolbarHandler.js > diff
   $ patch -p0 -R <diff
   patching file linkToolbarHandler.js
   $ cmp linkToolbarHandler.js.bak.old linkToolbarHandler.js
   $

Altered how?  Is it a LF versus CRLF problem?

Looks like a Cygwin problem to me.  Something with binary file mode,
perhaps?
