Even i write a wrong exe file name bcomp1.exe, git still use bcompare.
 
[diff]
    tool = bc3
[difftool "bc3"]
    cmd = "/cygdrive/c/program files/beyond compare 3/bcomp1.exe" "$(cygpath -w $LOCAL)" "$REMOTE"

$ git difftool/usr/lib/git-core/git-mergetool--lib: line 124: bcompare: command not found

I found the reason. because bc3 is a special name, git call bcompare internal.change the name bc3, it works fine.

That's right. We have difftool.<tool>.path for this use case.  It lets you redefine the path to the tool (e.g. bcompare).
