mergetool--lib: specialize diff options for emerge and ecmerge

davvid · gitster · commit 4481ff048df4 · 2009-05-09T08:25:22.000-07:00
The ecmerge documentation mentions the following form:

	ecmerge --mode=diff2 $1 $2

Since git-difftool is about diffing, we should use that instead
of --mode=merge2.  Likewise, this drops the $MERGED argument to
emerge, as discussed on the git list ($gmane/117930).
