If the file we are trying to merge resolve is in git-ls-files -u, then
skip the file existence test. If the file isn't reported in
git-ls-files, then check to see if the file exists or not to give an
appropriate error message.

The git-mergetool program can be used to automatically run an appropriate
merge resolution program to resolve merge conflicts. It will automatically
run one of kdiff3, tkdiff, meld, xxdiff, or emacs emerge programs.
