[PATCH 1/3] mergetools/kdiff3: do not use --auto when diffing

The `kdiff3 --auto` help message is, "No GUI if all conflicts are auto-
solvable."  This flag was carried over from the original mergetool
commands.  diff_cmd() is for two-way comparisons only so remove the
superfluous flag.

This one is not RFC; just a trivial fix.
