Changing diff/merge tool

I have been using Winmerge for years. Never expected that I would find any limitation with it. But it is failing to show diff view of c file modification in git repository with tortoise front end.

Moving to DiffMerge from SourceGear.

Though licensing is not so encouraging, it is a proving to be a good choice.

Shell integration is neat. No noise in diff view. Advantage with reference view and edited view.

So far so good.
