SKIP-WORKTREE BIT
Skip-worktree bit can be defined in one (long) sentence: When
reading an entry, if it is marked as skip-worktree, then Git
pretends its working directory version is up to date and read the
index version instead.
To elaborate, "reading" means checking for file existence,
reading file attributes or file content. The working directory
version may be present or absent. If present, its content may
match against the index version or not. Writing is not affected
by this bit, content safety is still first priority. Note that
Git can update working directory file, that is marked
skip-worktree, if it is safe to do so (i.e. working directory
version matches index version)
Although this bit looks similar to assume-unchanged bit, its goal
is different from assume-unchanged bit's. Skip-worktree also
takes precedence over assume-unchanged bit when both are set.
