checkout,merge: disallow overwriting ignored files with --no-overwrite-ignorend/ignore-might-be-precious
Ignored files usually are generated files (e.g. .o files) and can be
safely discarded. However sometimes users may have important files in
working directory, but still want a clean "git status", so they mark
them as ignored files. But in this case, these files should not be
overwritten without asking first.
Enable this use case with --no-overwrite-ignore, where git only sees
tracked and untracked files, no ignored files. Those who mix
discardable ignored files with important ones may have to sort it out
themselves.
