git stash: avoid data loss when "git stash save" kills a directory
"stash save" is about saving the local change to the working tree,
but also about restoring the state of the last commit to the working
tree. When a local change is to turn a non-directory to a directory,
in order to restore the non-directory, everything in the directory
needs to be removed.
Which is fine when running "git stash save --include-untracked",
but without that option, untracked, newly created files in the
directory will have to be discarded, if the state you are restoring
to has a non-directory at the same path as the directory.
Introduce a safety valve to fail the operation in such case, using
the "ls-files --killed" which was designed for this exact purpose.
The "stash save" is stopped when untracked files need to be
discarded because their leading path ceased to be a directory, and
the user is required to pass --force to really have the data
removed.
