What compiler and optimization settings are you using, and what is the
hardware platform?  It seems strange to me that you would get any
noticeable speedup from this change.  Most C compilers are supposed to
be reasonably smart about optimizing subscripted pointers.

Also, how about using tmpbuf as the moving pointer, instead of
interchanging the roles of tmpbuf and buffer as you did?  That
seems a bit confusing.

Finally, as Bruce noted, we prefer diff -c output for patches.
It's safer to apply that way --- the plain diff format fails
too easily if there have been any nearby changes.
