The default patch file viewer is messy (ie. no side by side diff view etc). I tried setting the path of beyondCompare exe in \"Settings->Unified Diff Viewer->custom\", but beyon
I've never found any, but the solution that I usually use is to simply apply the patch file to a pristine checkout of the tree, and then do a "regular" diff (my preferred tool is diffuse) to review the changes in context.
The problem with "raw" patch files is that they only provide a few lines of context before and after the change, which often isn't enough.
If you don't like the patch, simply revert the changes and don't commit!
