avoid warning in diff3.c

[Jim Meyering]

Here's a tiny patch to avoid this warning:

  diff3.c:1409: warning: format not a string literal and no format arguments

2006-03-12  Jim Meyering  <address@hidden>

        * src/diff3.c (output_diff3): Use fputs in place of fprintf
        to avoid a warning from gcc -Wformat-security.
